Harry were walking to the Strange mansion, being in the hurry that he was he did not get much of a good look at it, it was relatively modest for a manor, very boxlike and compact, the walls were made of large stone blocks up to the half way point of the first floor, and along the vertical edges of each wall. Over that up till the roof were bricks painted a light cream colour.
Under mage sight the house was a different story.
Each of the stone blocks and every one of the roof tiles were glowing with the the heavy runes needed for warding. The wards here were extensive from having those without magic unable to see it to the massive wards to stop magical intrusion.
He was meandering through the streets a little bit in front of the mansion, Strange and Clea, his advanced senses allowed him to hear that they expected some kind of payment for defeating Dormammu.
In his mind a few hours in the library would have been enough. For an immortal, knowledge was really all he needed.
He looked at the house again, having learned how the magical eyes work, he was able to look through the walls and make sense of the massively expanded insides.
The house was mostly divided between three uses, artefact rooms, libraries and living space, however there were several ritual rooms and a few large storage rooms.
All he really wanted for payment was to spend a few hours in the library and artefact rooms.
With his watch he could read the books and his hexQuarters should allow him to understand most of the enchantments on the artefacts, in fact they could understand the magic used by the Deathly Hallows.
The Deathly Hallows were very simple in truth, the wand only negated most spells used on the wielder and cast spells that could not be blocked by shields, the invisibility cloak only had self repairing charms and a special enchantment to replenish the magic in the demiguise fur.
The stone was the most powerful, and the only one that used death magic in the least, it was partially in the afterlife and whenever someone is called it creates a golem of mist based on the the image of the person summoned.
Joe walked into the house and sat down in one of the chairs. Before turning to Clea and Strange.
"As you know since you have approached me for aid, I require payment. Secondly do you wish for me to set up a Nexus between this dimension and the dimension that Clea comes from. For this I will require payment. Should I do this for you I will spend one day looking over your library and artefact rooms."
Quickly skimming across Strange's mind he picked up mention of a powerful scrying tool by the name of the Eye of Aggamotto, he made sure that it would be placed in the artefact rooms.
The terms were set and Joe was lead to a small room in the center of the Sanctum
Sanctorum where the portal would be placed.
He first procured two round mirrors each about as wide as a door was tall. That was surprisingly difficult, he eventually had to use an old masonry spell to merge several mirrors together to make the pair. Eventually he managed to create the circular mirrors and add stone borders.
He then placed them back to back, and began carving a large number of runes on it before charging them, he even included part of a fedilus charm, so that it could only be seen by Strange and Clea. He finally separated them, and placed one on the wall before teleporting himself and Clea to the Dark dimension.
Hanging the mirror in the location suggested he brought out his scythe become cutting though the mirror. Suddenly the glass began wobble and the image began to turn black and red swirls began to appear before the portal finally managed to level out leaving behind the image of the other mirror.
Harry stepped though the portal and found himself in the Sanctum Sanctorum, Clea quickly following. He began walking towards the Library He stopped in before touching his watch, a quick pull on the knob and time stopped.
He spent, what felt like to him several years in that library, it was the most extensive one regarding magic in this dimension and had quite a bit of knowledge, magic was pretty static over the different dimensions, and Joe was one of the most knowledgeable at the moment.
The enchantment sections were something he had never read before and being immortal, knowledge is all he really wanted. Money and stuff, meh, he could do that himself.
He looked over several of the artefacts, a nice cloak of levitation, a ring that had an immense ability to store magic, a potion that could cure madness and several staves and swords with interesting capabilities.
The Library was the most interesting, especially the scrolls that were warded, with him being out of current time, the Wards could not detect him.
He read about lost civilisations the different gods and goddesses of this world.
He found a lot of situations very similar to himself except they became gods over time and did not suddenly discover that they were immortal, though there was an ancient Vampire who became immortal and could not get rid of it.
He mainly focused on the magic used here, turns out almost no one here used their own magic. Natural magic was produced magical animals, and to a minor extent all living things.
Sorcerers usually used ambient magic, thought hey could call upon magic from specific sources, Sorcerers who became gods basically just had the magic of the universe they worked inside of at their disposal, local deities had the magic of their worshippers.
Joe was special in this regard because not only does he have his own magical core which was large enough to surpass most local deities and was still growing.
Though he would have to check after defeating Dormammu, he did not know what the effects of absorbing a demon powerful enough to be counted as a minor god were, on top of the large amount of magic he absorbed from the light demon.
Most of the spells used by the magicians here were in three categories, binding, explosions and elemental effects.
Well on the plus side he learned a lot more about elemental manipulation.
The only other major portion was enchanting, and that was something that Joe drank up greedily.
However the single most important scroll was a focus on the mind arts to help him organise his mind and improve his recall.
Joe spent several hours properly sorting his mind so that the massive amount of knowledge would not make him forgetful.
He managed to cover almost everything, a few trips back in his home dimension and he would be fine.
He began looking though the lore on the magical creatures next, the magical creatures were surprisingly rare in this universe, and the only dragons are a small number of Greater Wryms.
However beyond the occasional presence of a Greater Wrym, nigh omnipotent beings are extremely rare in the world he came from.
He could safely say that he was one of the few beings that could detect magic off of the planet earth.
Nicholas and Pernell had been giving him some instruction in Potions, Runes and Alchemy, and he was grateful for that, he wouldn't have been able to create the nexus without that knowledge.
Though After reading about the theory of how these people enchanted portals, he had a much better understanding.
He even snuck back and hexed the portal so Strange would always exit upside down.
He was bored so sue him.
Finally he came the strange Orb of Aggamoto and the Eye of Aggamotto, he looked over them, they were both very similar though the Eye had a limited range.
The eye was a localised pulse of magic on the astral plane that worked much like sonar, but with the ability to see in color, which was due to the magic used in the pulse as well as the ability to see though walls, wards and cloaking abilities.
The overall effect was an 'all seeing eye' though at a very limited range.
The Orb however had the effect of sending an Eye to send back images, releasing a magical bolt along the Astral plane which exploded releasing a pulse that acted in the same way as the pulse from the eye.
For all intensive purposes, Harry did not need the eye whatsoever, his training to create the prosthetic eye allowed him to similar things without any additional tools.
Finally Joe decided to call it quits and walked out.
