Goran laughs at the rapid back and forth of the group "You seem to be developing quite a cameraderie, the dean does have a habit of 'accidentally' putting people together. I think you'll also find that much of the learning you'll do here will come simply from interacting with the other students, learning their ways and your differences. That is, some believe, where the true learning begins. Anyways, I'd better answer your questions, I have places to be, and I'm sure you all want to stow whatever you've brought with you before continuing your tour."
Goran turns to Coravin "If you wish to do any long term or potentially dangerous conjurations, you'll need the aproval of one of the Master Conjurers, though anything minor won't be an issue. There are many wards around the school to prevent unauthorized conjuration, so if you are wondering about anything in specific, just attempt it. If it doesn't work - well, then you'll know to contact the Masters and ask for their approval.
The library is.. an interesting place. I've been here decades and not read a tenth of a percent of what is available. In fact, I doubt even the librarian himself doesn't know how to find every book. You could get lost in the stacks for days if you didn't know where to look. I imagine there are spellbooks in there, but any easily found have likely been taken for use by other students. No harm in looking, though."
He then turns to Aussir "Ah my little Drake, you have much to learn if you wish to grow like your cousins. The greater dragons know that strength alone will not keep their scales from becoming some dragonslayers trophy. They use magic and cunning as well. They outsmart the slayers, set traps for them, and so forth."
The Ogre smiles widely and bows to the group as he excuses himself
"And if any of you do wish to speak to me further, I'm sure Miss Arin can find you a copy of my schedule."
"Gawd that guy talks a awful lot don't he? Gota admit he's smart though. Well, here we are." Arin turns a corner and you enter a large circular room which appears to have no ceiling, but the floor around the outside is covered in glowing circles of various sizes. "This's tha tower, jes step on one'a the glowin disks an say yer name - or tha name o' the person ya wanna visit - an it'll take ya t'the right room. Rooms'll only open fer their rightful owner or a teacher, so don' even think 'bout breakin inta somebody elses stuff. Allright, lunchtime soon so's y'all best drop off yer stuff an I can lead ya to the cafeteria."
