Hi there and welcome! I'm Lily and I'll see if I can throw a few people your way (sorry for the late introduction, been away a bit due to family stuff).
Oh, I also have to move my character's profiles from the old system too, but I'll do that right after I post here. lol
Lorelei - She's a 'sixteen year old' sweetheart who is considered new at Tally since the end of last year. But some people would also know that she is the granddaughter of the Minister of Magic, and daughter of music and movie star, Jezebel Blair. And that only a year ago she was attending Bilby and was a rather odd child. But now she's a rockin' teen, which is confusing the hell out of some folks. Either way, she's got the emotional and mental development of an adult most the time, so it seems to fit. Anyway! Her mum and grandpa are popular Spencer Alumni, and she's a little sad coz she was placed in Sturt, but figures it's because she needs to stay near her aunt/counterpart Lauren, who is almost an opposite of Lorelei. Lei herself does love to make friends, she will try to help anyone who looks like they're in trouble, and will join in on pranks if invited. Always up for tossing her at people and seeing how they interact.
Aisling - Is not yet a completed character, but she is on the way, and will be interesting to see how that goes because she has never been in the human world. To stay tuned! They could even end up in the same House!
Caitlin - The school counsellor, originally hailing from Ireland, also a criminal profiler, psychologist, and a famous crime novelist. She's pretty easy going despite the serious-sounding titles, and her door is always open to any students who need someone to talk to. She's very motherly in nature, and always has cookies in her office.
Cassandra - Was in Spencer just last year, and graduated. She is also Alex Winfield's (another Spencer) wife, and Caitlin's niece. She is likely to visit the school and hang out. I hear that she may be given a job helping out in the library or something if she gets too bored (and considering Adele is teaching HoM again, and Cass is pregnant so she has to put dancing college off for a year). Likely to stick out because of both her head of blood red hair, and her general bright nature. She's tons of fun almost all the time.
I have a bucket load of other characters, some of which might also be good candidates for interaction, but going with the easiest ones to think of for now. Let me know if anything else catches your interest!
