princelingblack is Regulus Black. Rather quiet, introverted, and puts on different personalities to suit different people. He doesn't know how to be his own person aaaand won't figure out how until it's far too late for the boy. :/ Currently under the stress of his family members trying to kill each other at dueling club. He's a fifth year Slytherin.
drink__me is Rosmerta Winethrop, Rose for short. She's usually a happy go lucky sort of girl and is Hufflepuff defined. She's kind of quiet right now as she lost her owl in the great owl massacre and, while she's caring for one she found, she still misses him. She was born and raised in Hogsmeade and her parents own the Three Broomsticks. She's a seventh year Hufflepuff.
fenwicker is Benjy Fenwick, future Order member. He's a complete and utter geek and wants to be a Healer when he finishes school, even if he's struggling with Herbology. His father is a muggleborn (former Gryffindor, works as a photographer for the Daily Prophet) and his mother is a squib (works as a nurse at a muggle hospital). So he's pretty passionate about equal rights. He's a 6th year Ravenclaw.
moredeadlythan is Rebecca Gilligan, Becca for short. She's the future mother of Blaise Zabini and niece of the CoMC professor. She's independent, loves the finer things in life, and although she's a purist, she's not a Voldemort supporter. After all, what's the dark lord done for her lately? She's a 5th year Slytherin.
