For friends, I can offer
Farah Kattan. She was a novice, but after two decades of fruitless development, she's adopted the greys of the Warder Yards. I can't say I know what she's like now, but she was tomboyish. I can't help but think the Warder Yards will only double-down on that aspect of her personality.
If you want hijinx,
Kaira is the worst sort of influence. She's already run away from the Grey Tower once, and she's found herself in
a sticky predicament right at this moment. She's a novice, but she's about as rebellious as one can get without being kicked out.
For channelling threads or just other interactions,
Zarayne is an Oathsworn Yellow. She's a genuinely friendly sort, although her whole Aiel thing can make her a bit awkward. Or if you like playing with cats,
Elia is about as catty as my characters get. She especially likes to play with novices like a cat plays with a ball of string.
Lastly, I have
Ravak t'Sha'hal Darrow, patriarch of the Darrow brood for his many, many sins. If you need some fatherly advice, education on how to poke people with swords, or want someone to sniff out your crimes, he's available.
