Well, what type of magic? You do know quite a range.
In general, you are good at non-advanced stuff, simple spellforms and general elemental shapings and the easily weaponised stuff. It was, in fact, what you spent a large amount of your time doing at the Guild.
Your hobbies included magic, specifically alchemy (students were encouraged to have a supplementary-to-syllabus hobby of some form), basic divination and working neurotically on reducing your Signature.
You even remember your final lower exams. You used the most complicated piece of alchemy you could find in the textbook, adjusted it slightly and presented it as proof of skill and ingenuity. You don't recall how well it did.
Erm, there's just clouds and the Luna Sanguis.
You have found a bunch of broken bottles of various types, and a vial of dark blue opaque liquid with some runes on the cork usually used for preserving food and alchemical reagents. Personally, you hoped for some food, but hey, it might be useful.
You can't sense any magic coming off it, but it is in a glass vial.
You don't know what a rocket is, so you turn to look at the tower.
It looks a bit weird, and something about it pulls on something at the back of your brain, but otherwise it appears to be a normal tower.
