When life gives you Mandos, make Mando'ade
It's really (and justifiably) tough to get anything through the Factory/Codex that beats ysalamiri in the great game of rock-paper-scissors. Connory's last working group along these lines had some limited success, but there's room for more. I'll be kicking off another working group thread and making the last one's research available IC. The working group's OOC goal is to find ways to beat ysalamiri by discovering firm but obscure canon or getting a submission approved. It's a significant challenge, success is not guaranteed, and that's why it's fun.
