Valendil is a playable start but there's also an old picture of him with a singing slave that doesn't seem to have ever been used in the game for an assignment. But recently the art was upgraded and there are variations of feminization, and the new art is used for Shark of the Cards, so maybe they're planning on adding special content to that assignment.
I'm not sure about Alucasta but Alis might refer to Alison, the fae from gorging on the green. If you're getting this info from the game files, sometimes Bedlam puts images in those for assignments that aren't in the game yet.
