Hello Trinity! I'm Lis and I have two people here, one of which Irys would have a fair amount of interaction with. But first, let me say welcome to the game!
Viola Rosier (this journal) - Irys and Viola probably knew one another before this year and now they're going to be quadmates! First things first, Viola is the daughter of Pansy Parkinson and Emmanuel Rosier, both purebloods. I'm up for some sort of relation there if you're interested. Viola has a older sister that was Irys' house/yearmate at Hogwarts. Just prior to the start of the game Viola was meant to get married, but broke off the engagement/called off the wedding. Irys and her family were probably invited if Pansy had any say in the matter (and she had a lot of it). This has sent Viola into a bit of a tailspin, but she's hoping to get back on an even keel soon. Viola's a second year majoring in French and Wizarding Culture/Studies and is a former Gryffindor. Viola tends to be quiet and circumspect, but can be a bit dramatic if under a lot of stress. Lots of information I know, but I'm open for anything here.
Will Longbottom (icarus_me) - He is the first year son of Hannah Abbott and Neville Longbottom, former Hufflepuff. He has an older brother in Irys' year. He's loud and can be abrasive and annoying. Will enjoys egging people on and doing things impulsively. He randomly comments so lots of random interaction there. He doesn't mind being an enemy.
