[@Metamore] hullo! i'm super glad everyone's enjoying their chars and having fun <3 as for seren, it looks like they are outside? right now, it's not the best place to be, and the academy is very firm when it comes to fighting, but as a first year, seren could probably get the middle/back of the crowd and mostly be alright/protected. as stated before, there is little/none magical barriers, but the returning students do a good job of fighting back monsters.

as for worst-case... I would intervene before your character could die/get possessed (though possession can be reversed!), so you don't have to worry, but yes, death/injury (both mental and physical; spirits also must get into people's minds to possess them) is worst case. the threat is very real.
