A/N: I know Aldertree plays a completely different role in the books, but I decided to use the character of the TV show Aldertree tree as a bad guy in This fic. Raj also makes a appearance as well. Enjoy!
"Magnus, what the hell?" Alec said, bewildered, "Does it hurt?"
"No I... I don't even feel it," Magnus said softly, looking up to meet Alec's eyes with a curious and concerned look on his face.
"But that doesn't make sense. If no one drew that rune on you, how is it there?"
"Lets go show Clary. She could help us," Magnus said, getting up to get his coat. Alec followed.
Magnus opened a portal, grabbing Alec by the hand and taking him with him. Alec could tell that this was scaring Magnus. The use of angelic runes on a warlock was very odd indeed.
When they arrived at the institute, they were met by a typical sight. Clary and Jace, of course, all over each other against a wall. Alec looked down at his hands while Magnus cleared his throat loudly, commenting, "It doesn't take you two long to get at it again."
"Magnus Bane," Jace smirked, turning his head towards the pair, "Seems a little hypocritical coming from you. I recall a certain hickey."
"Jace," Carly scolded, "Is everything alright, Magnus?"
"Of course, Biscuit, but it seems to be that your rune had an effect on me too," Magnus stated, showing his wrist to Clary.
"By the Angel, would you look at that," a voice behind them said curtly. The four of them looked over to see Aldertree, the current, annoying head of the New York institute give Magnus the death glare.
"I will have to report this to the clave. I don't know what spells you have done, downworlder, but no one here appreciates our runes on a... demon of sorts."
"Leave him alone. It isn't his fault." Alec said with a new found confidence, "It's because of Clary's new rune. She put it on me and, in turn, it went on Magnus as well."
"Looks like Clary might get in trouble too. I know your precious step father is also a downworlder but I wouldn't expect this from you, Clarissa." Aldertree said matter-of-factly, shaking his head in a disappointingly evil way.
This caught Jaces attention, "You won't touch Clary-"
"I can do whatever I please, Herondale, now if you don't mind I need Magnus Bane and Clary Fairchild to come to my office." Aldertree said curtly, making his way towards the door.
"I don't have to follow your rules, Nephilim. This is between Alexander, Carly and I. Now if you don't mind-"
"I would be happy to send a long, lengthy report to the inquisitor about their precious High Warlock of Brooklyn disrespecting my orders. And knowing your... relation to him, I don't know if he'd be to happy with it. Come with me, warlock." Aldertree said in a menacing fashion, opening the door.
Magnus and Clary shared a look before following Aldertree out, Magnus muttering, "who shit in your cereal..." making Clary giggle.
Once the trio had left, Jace and Alec made their way down to the main hall, where the met with some of their colleagues to discuss demon activity. Alec had almost forgotten about this whole situation until he heard a frightening familiar scream, coming from Aldertrees office.
"Magnus!" Alec proclaimed, running towards the noise. When he opened the door, the mix of worry and anger hit him like a truck.
Magnus was being held down by Raj, in a stiff wood chair. Clary was being held back for helping Magnus. And Aldertree was putting his stele right against the warlocks skin.
