Yuppers! Now we just need the fourth member and figure out a team name. If we do use Gren, Prisilla, and Serara, we have the letters GPS, 

If we could get Robert , we could be Team PRGS, or Team Progress.

If we can get Yael, we could be Team GPSY, or Team Gypsy.

There is likely other combos, but I can't figure them out right now.
