Elf CG Teaser

Art by Applehead/Mistimagi

This will be getting into the v27 update, though given current elf content the variant with the third elf will be in use at a later time, but the CG will be fully set up so utilizing it later will be easy. Much like the ancilla CG implementation I'm gonna need to mess around with how the base elf is set up so it all works properly, given they're still using the outdated non-layered expressions method from way back.
