Several people gave out very interesting ideas and I thank you all for the help. Some of them actually overlapped some of mine; so I'll incorporate them into my own.
Sorry if everyone already knows this but I'm going to put up a lecture of Oblivion. I'm undecided as to the Mad God is who Colbert is looking for.
The stealth system in Skyrim is lackluster. I can shoot someone with an arrow and a few moments later "I guess it was just my imagination." This video on Youtube is pretty much the same as the actual game (watch?v=lHbF9ynGZV0) And we all know where the second arrow hit.
"Get your hands off me!" raged the well-dressed prisoner. "Do you have any idea who I am? I'll see you hanged for this!"
The two white cloaked guards ignored his threats. They knew their duty and they were given explicit orders by the Jarl himself to bring the man to him. Their rough hands had a tight grip on the man's shoulder as they pushed him through the door.
"Here he is; Jarl Kraldar." The Jarl gave a nod of acknowledgement as they brought the man to his knees in front of him.
"Are you the Lord of Winterhold? I demand an explanation for this treatment." shouted the man.
Kraldar picked up a parchment from the small table beside him. "Intimidation, assault, murder and resisting arrest." The Jarl gave a low whistle. "Quite the list of crimes you got yourself there boy."
"Who are you calling boy? I'm the Viscount of-"began the man. The guard to the left of him cuffed him over the face.
"How dare you commoner! For you to strike a nob-"The guard struck him again, a lot harder this time. This time it drew blood as the guard's armoured fist connected with the noble's face.
Undaunted; the Viscount spat out the blood welling in his mouth; his eyes came to rest on the Jarl of Winterhold. "Aren't you going to stop this?!" he demanded.
The Jarl returned his stare; his gaze cold as he looked down at the prisoner. "This time use your blade. Don't kill him though." he commanded of the guard.
The Viscount could only watch in horror as the man drew a long steel blade out of his sheath. The free guard placed his other hand onto him; holding him in place. "By the Founder; what are you doin-"
The sound of the flat side of the blade hitting the Viscount's face was audible. The sound of the noble's jaw breaking as the cold steel caught him on the cheek.
The Jarl's face was dark as his guards forced the man back onto his knees. His face was a mess as blood dripped of it; though, thankfully, the man stopped taking.
"Now listen, boy, I will not have you go murdering my people just because they were an Elf. I don't know how you deal with crimes in Tristain; but I know how we deal with them here."
"Blut shwe was an elfwe!" gargled out the man. The guard didn't hesitate to put his foot to the Viscount's chin.
"And your Princess has given me permission to deal with all trouble as I see fit. So your pretty title cannot save you here." said the Jarl with distaste.
Waving with his hand; he summoned another pair of guards. "Take this fool to the marketplace. Execute him there so that all those Tristainians can see."
Picking up the list of the man's crimes; he handed the parchment to the nearest guard. "This is his crimes; I want you to read them out before you kill him."
"Ywou cwan't dwo thwis! I'mwa thwe Vwiscwount of-" protested the man in ineligible speech.
As the guard made to hit him again; the Jarl stopped him first. Slowly getting off his throne; he walked precariously to the kneeling man.
He crouched down in front of the Viscount and grabbed his head with both hands. "Listen, boy, I couldn't care less who you are. You can be the King of Skyrim. No the Emperor himself for all I care. But when you kill one of my people…"
Without finishing his sentence; he drew his head back and brutally head-butted the Viscount. Kraldar could hear the man's nose breaking from the force of the blow.
Getting back up; the Jarl wiped the blood off his head. With one last disdainful look; he spat on the broken Viscount. "Don't make it too quick." he ordered offhandedly.
With that he returned to sit on his throne; not even bothering to look at the condemned man.
Once he was seated back on his throne; the Jarl turned to his steward who was ironically an Elf. Though the steward tried; he couldn't get rid of the remnants of a cold smile. "Who was the man again? The Viscount of what?" he asked the steward.
"Of Hemstra." finished the steward.
"The Viscount of Hemstra then. Draft a letter to Tristain; tell them they have to get better control of their nobles and that they just lost another one of their nobles. This is already the fourth one I had to kill this month." ordered the Jarl.
"I shall see to it at once." answered the Steward; as he left his spot by the Jarl's side.
The only two Tristainian students were back in their usual classroom. Professor Colbert was also present as the Archmage had instructed their teacher to tell them important news.
This was after their discussion on Siesta's magic which ended with him dismissing them after the former maid told him about her grandfather. While he didn't specify what her grandfather had to do with magic; she was certain he knew, or at least had a good idea of it.
He told her that she could research what was special about him by herself as a project; with only a few hints to steer her in the right direction. Those being something about it being common on the Hammerfell-High Rock-Skyrim border and that her grandfather practiced a powerful form of magic that could match the Elder Scrolls; whatever they were.
"First off: Almost all forms of magic are practiced here as long as they don't endanger anyone else" said Onmound.
"And that includes Necromancy." He finished; his face prepared for what was going to come.
"WHAT?" exclaimed Louise in surprise, getting up from her chair in surprise. "But that's…"
Her Nord teacher folded his arms. "Yes I know. It goes against the doctrines of your Church. It's frown upon by most here too; but it is allowed." interrupted her teacher.
"So we have to learn…" started Siesta, whose response was more tamed.
Onmound waved his hand in negative. "No; you don't have to learn necromancy. But try to understand that since it does come under Conjuration; you will come into contact with necromancers." reassured the Master Mage.
"But how can your people be willing to raise the dead?" asked Colbert, face showing both concern and interest at the prospect of being back the deceased.
Onmound gave a casual shrug. "I'm no necromancer myself so I can't give an in-depth insight as to why they chose to practice the necromantic arts."
"But you can't deny that it is useful. An undead servant wouldn't need anything a living one would require and I suppose there are some that wants to see their dead loved ones again." he explained.
"But still…" started Louise "That isn't an excuse to drag back dead people to life". Bringing back the dead was an insult to everything alive. Undead was a perversion of life and just wrong.
"There's no need to tell me your arguments as to why it is wrong. I personally don't like it myself but I feel that it is important to tell you since you Tristainians seem more squeamish about the darker sides of magic." interrupted Onmound.
"But why would you tell us this now instead of earlier?" inquired Siesta.
"Because I'm going to show you the Atronach forge. It's usually used to bind Daedra to Mundus but occasionally there will be someone creating an undead servitor. I rather you be prepared for whatever happen there. " answered their master.
While Louise and Siesta was not familiar with the term; it was clear that Colbert was. His face was filled with what seemed like childish excitement as he thought of the prospect of watching mages bind otherworldly spirits to this world.
"An Atronach is a powerful form of Daedra. What makes this one special, however, is that they are made of a single pure substance and that, unlike other Daedra, hold no allegiance towards any of the Princes of Oblivion." explained Onmound for the benefit for the two ignorant girls.
Louise then raised her hand up into the air in question. "What's a Daedra?"
Onmound was confounded before slapping himself in the head. This wasn't a good reflection of his teaching skills if he forgot to even teach them about Daedra when he planned to go the Forge.
"Well… Daedra are supernatural beings that inhabit the planes of Oblivion. Oblivion itself is just collective term for the number of known different planes outside of our own. In general; they can't enter our own plane unless someone summons them. He started.
"Essentially anything not from our world is Daedric and different planes are of Oblivion. This world of yours: Halkengenia, would be considered a plane of Oblivion simply because it's obviously not our world and you and Apprentice Siesta; Daedra." He continued as the Tristainian 'Daedra' seemed put off by being compared to a supernatural being.
"There are probably thousands of planes that we are not aware of but we are aware of only sixteen… seventeen now counting Halkengenia. I'm not certain about Halkengenia but all the other planes are ruled by a Daedric Prince. Now before you can ask; the princes are the most powerful of the Daedra. Enough so that you can compare them to gods in power."
Onmound stopped there and took a quick sip of mead before he continued. While he was aware of the new popular 'tea' among the older mages; he still preferred his mead. Tea tasted good and all but it just couldn't give him that warm feeling in his stomach when he drank mead. "Now; there's one defining feature of the Daedra. And that is their immortality."
Again Louise jotted her hand up. "How are Daedra immortal? Are they all spirits?" she asked.
Onmound shook his head. "They are not spirits though it is similar. Essentially it is the soul or animus of a Daedra that is immortal. As long as their soul is still alive; then they can regenerate their form back in Oblivion. It's theorized that if you kill a Daedra's soul in Oblivion then they would die but since not many would willingly travel into the planes of Oblivion; it has never been confirmed."
"Is Oblivion dangerous?" asked Siesta; before she remembered she was meant to place her hand up first. "Ah… I'm sorry." she said; flushed.
"It's no problem; just remember next time. As for your question: yes. Few ever travel to the planes of Oblivion and even less return to tell the tales. The largest number of people entering the planes would be during the Oblivion Crisis; where large groups of soldiers travelled in to close the gates."
"And what about the Hero of Kvatch?" asked Colbert, his presence forgotten until now.
Onmound scratched the back of his head in embarrassment. "I'm sad to say I don't know too much about the details of the Crisis. I know that the Hero was probably the one who ventured into the gates the most and that he helped Martin Septim defeat Mehrunes Dagon but that is all I can remember."
"Do you know where I can find more information about it? I've exhausted the library but I can't seem to find where the Hero disappear to." pressed Colbert.
"You finished all them? Uh… have you tried asking Urag gro-Shub?" suggested a surprised Nord. Granted that there wasn't that many books dedicated to the Hero for some reason; but there were hundreds of them on the Crisis itself.
"Yes I've already tried that." replied Colbert.
"I'm afraid I don't know then. Sorry about that." apologised the Nord. Colbert nodded in understanding. It wasn't his fault anyhow.
"Did you uh… actually finish them all? All few hundred of them?" questioned Onmound, before he started on his lecture again.
"No. No. The majority of them share the same information so I only actually finished the first ten or so. I mean that I've searched all the books here but none of them provide a reason for the disappearance of the Hero of Kvatch." explained Colbert, as if it was normal to finish ten large text books within a single working week.
"Ah right. That makes more sense." Onmound sighed. He was sure that the Tristainian Professor was a genius, if a bit absent minded. But to have read hundreds of textbooks in just a week after he just finished learning the language…
"Where was I? Ah that's right. The planes of Oblivion are, in general, a very dangerous place for us mortals. Even if some of the Deadra are friendly or, in the case of the Daedra Prince Azura, benevolent; it does not mean that their planes are safe. Following on from Azura as an example; her plane is Moonshadow. According to the old records; it is a place of unimaginable beauty and made up of impossible shades of colour and perpetual twilight. While this may sound non-threatening; it doesn't change the danger as nearly all who left the plane came out either half blind or mad." warned Onmound.
"So all Daedra are bad?" asked Siesta; this time making sure she raised her hand first.
"Not exactly; despite common belief not all of them are what we would call 'evil'. Remember that they are all within a different plane to us. Think of how Halkengenia's stance on Elves differs to ours; since we are of different planes we will have different views on how we see the world. So we cannot assume that the Daedra share the same morality as us."
Flicking his hand; a ball of fire appeared. "Now say that I hit Apprentice Valliere with this and severely burn her. We can all see that what I am doing is wrong am I right?"
Seeing that his students were following along with him so far he continued. "Now a Daedra won't see it that way. Say that I was a Dremora; this type of Daedra has a particular dislike of us mortals and if hit Apprentice Valliere unprovoked like this; they would consider it a good deed as I got rid of, what they consider, trash." By now they had lost him.
"How are they not all evil then?" asked Louise; dutifully raising her hand as always.
"Well that probably wasn't the best example to say they're not all 'evil'. But take the other Daedric Prince I mentioned before: Azura of Dawn and Dusk. She's been known to aid her followers and is what people consider a 'good' Daedra."
Seeing that they still didn't understand he sighed and took another drink of mead. "The point is that Daedra are outside of our moralities. What we consider bad may be good to them or otherwise. So it is incorrect to label them with 'good' or 'evil'"
"So then which ones aren't… as 'evil' as the others." inquired Louise.
"Well… Azura is…"
This will be a spoiler for future updates. Don't read if you don't want to know. This is also just conjecture so it's liable to change.
I'm thinking of having Gah-Ei go out in a blaze of glory later. It would be suitable considering what he is capable of. It'll be him versus and army and despite how powerful he is; I think army would win in the end. So it's either holding the Reconquesta army off at Newcastle while the Royal family escapes, during the defense of Tarbes riding a dragon, during the invasion when all hell breaks loose, or a completely new scenario made up by do you think?
