SpoilerX'Wahaii Odh: Name can be changed (as long as it begins with X' !). Seeker and Mother of the twins.  She came off as rather strict with the children because she did not want anyone finding out about the girls not being full Seekers.  The only physical requirement is that she has dark purple hair.

Keeper Male: Name is up to you! As well as personality/how he would react to finding out about the twins - Father of the twins, even though he has absolutely no idea currently. The physical requirements for him are light purple hair and one eye light purple and the other dark purple.

Half Sibling: Name/Gender/etc is up to you, the only requirement would be that they are Keeper and have the same eyes as the father father. I think it would be interesting for them to discover they have another sibling (Even though they have multiple half siblings from the X' tribe, neither of them really see them as such-more like multiple cousins)

Other: Half-Siblings, Clan Mates, any people that you can think of that could help the girls!

Raeras is constantly traveling around and it could be interesting for her to run in to the Keeper male or a clan member/half-sibling, etc! Anyhow, there are still a few details that need worked out, but I would really love to at least get the 'ball rolling' so to speak ^^, and if you have any ideas at all let me know!
