This is a little belated from me, but better late than never, right? This would be Jay. I have two kids for you so far, though only one is at full character status.
Orion _protectorate is the third person traveling with Seajay and Filly. He comes from a military background and is kind of the stoic, stony-faced type unless you really get to know him. He's fiercely protective of those he cares about, so if anyone even thinks about harming Seajay or Filly, you will have him to deal with. You can read up about him here.
Then this lovely lady is Mouse minimouse. She's from over at DT. She'll be an NPC for this game's purposes as she'll be coming around with Grey to visit English, Yeates and Frankie. She's a little older now (19) and has grown up some (a.k.a. has a new PB), but she's still the same Mouse. And now she's actually with Grey, though that news hasn't been brought to Clayton yet! For those of you who don't remember her too well, you can read her original stuff here and her new stuff here.
I have a third in the works but she's not finished quite yet. And if anyone has plot lines they need/want filled, please let me know! I have too much imagination and don't know what to do with it, haha.
You can still find me on AIM under fannedblaze or email at inspired_by_words@yahoo.com. And my YIM is inspired_by_words. Hit me up!
