I don't really know if or when I'd find out through roleplay, but I am curious about what kind of security lapse allowed Efaen to get to the barium, then to the pool with it. I guess I can understand if they were so ticked off that they decided to punish Efaen themselves, instead of handing her over to Ossanlin, but I'm confused about how she managed to do what she did.
I'll try to give you the short version.
The barium was being tested and kept on an asteroid near the rebel base, where primarily Illim and Corliss were working on developing it. Efaen used her Terenia morph to steal a ship and pretend to be Terenia visiting Corliss. When she got to the asteroid research base she demorphed and knocked Illim and Corliss unconscious and stole two or three vials of barium. That's also when she acquired morphs of Mike and Daniel.
When she made it back to base she used morphing as her weapon again. When she got into the pool room to dump the barium into the pool it was in a morph of Edith, who is the base's resident kid -- she was about 12 at the time and grew up there, so everyone presumed she was harmless. Her mother was also infested, so it wasn't strange for her to be by the pool, talking to her Yeerk mother. Efaen dumped the barium into the pool -- luckily Myitt was there and managed to quarantine the pool before it took complete effect (and also shoot Efaen up pretty badly). The barium still managed to kill or paralyze a significant number of Yeerks, though. Including Edith's mother.
