Gregor Miststalker (or so he's called) is a member of the Cerulean Society with a bit of a mixed reputation - despite his association, there are a number of rumors floating around that he's done work for the king in a more official capacity, with exaggerated stories of heists and reconnaissance conducted around Varisia and the rest of the Inner Sea. He is rarely seen, more often heard of in whispers and wild speculation.
Which is why his letter to the headmaster was a touch unusual - someone like that, who clearly prizes sublety and anonymity, requesting to participate in a public event, was rather unusual. However, having secured his invitation, he seems quite confident that he'll be able to easily breach the wards and enter victoriously.
"Kaz, are you insane?"
"I don't seem to recall ever getting unduly mentally influenced by a foe we encountered, unlike someone I know." The roguish mage balanced the tip of a dagger on his finger, smirking.
"That was ONE time, when we just met! Give it a break. Look, I know we're trying to deal with this Acadamae idiot, but that doesn't mean going to Korvosa to try and bust into their school is a good idea." The more traditionally robed of the pair tapped his wand impatiently on the table.
"Oh no, it's encouraged, actually. They have a whole thing where they let people try to break into the Abjurer's dormitory."
"Still! It's dangerous and you damn well know it! And that's assuming they'd let you try, it's not like you're a local or anything."
"Oh, they'll think it's a local, alright."
"... Huh?"
"What? It's not hard to disguise yourself, especially if the person is a thief with a reputation for limited public appearances. And you guys can hold him for me while I assume his identity."
"Oh, yeah, kidnapping a local figure and masquerading as him deep in the devil-summoning academy, I'm sure nothing will go wrong."
"Look, let me put it to you this way, Franz. Point one: I am our primary means of transportation." With his free hand Kaz traced the outline of a portal, briefly shimmering with a glimpse of home. "Point two: When we all banded up to handle the warband that got us started on this globe-trot, we agreed we would allow our fellows time for personal matters."
"... I don't like where this is going." Franz crossed his arms, grumpy.
"Point three: I have not taken any of my personal time." Kaz had a very punchable face when he smiled like that. "So I go, you guys are basically stuck, yeah? Unless you wanna shell out a LOT of cash. And don't get me wrong, I hear Elysium is lovely this time of year, but wouldn't you rather I do something productive with my off days?"
"Don't get yourself killed."
"I mean, if something DOES kill me, then it would be doing that, as opposed to me doing something."
"You are so insufferable sometimes."
"Love you too, Franz!"
Kazren Fei has something of a reputation as part of the Starry Company, a group led by a devout priest of Desna who have worked tirelessly to ensure peace and provide protection to those in the more far-flung rural settlements of Varisia which might otherwise be vulnerable to the predation of horrors and warlords. He tends to downplay his own accomplishments to better suit his role as the group's infiltrator and mundane reconnaissance expert - he never had the patience for intense Divination, entrusting that to his friend Franz.
More recently, they have been away from home due to the activities of a diabolist graduate of the Acadamae who they have reason to believe has serious, world-spanning ambitions. Kaz had the idea to infiltrate at the Breaching Festival for just that reason - perhaps he could learn something that would assist them against their hated foe, or even just stealing a couple quality goods from the school grounds as a tax on allowing their students to cause so much trouble. If nothing else, he hasn't gotten to go on a good heist in over a year, and the prospect of a good challenge is very enticing to him.
Kazren is a Rogue 1/Conj Wizard 3/AT 9. I'm not completely sure on build at the time of writing, but considering the opening to this adventure, a magical rogue with enough skill points to help cover a caster-heavy party seemed like the perfect fit!
