Chellina
Mis-spelling of Gilina Renaez, the name of a guest-star character on Farscape played by Alyssa-Jane Cook. The mis-spelling crops up on the Aridor Slave Rescue game, where Chellina is one of the most highly sought-after characters.
I put this up after spending hours a while back, searching for information on or pictures of Chellina, and never getting any hits on anywhere except Aridor... Well, anyone else doing the same will hit this page too, and can go look for Gilina instead.
