Mimic

A mime who can imitate almost any dragon after observing them long enough. She has no voice of her own, but should she mimic another dragon long enough, she can steal their appearance and voice - and eventually snatch their existence for herself.

Notes:
- Uncanny ability to perfectly imitate a dragon's voice after hearing it once, though pronunciation/accent might be off if she gets into more complex sentences. The longer she hears a dragon speak, the easier it is for her to imitate them, nuances and all.
- Probably shows up to clans doing a friendly mime act; sticks around long enough to pick a dragon to mimic. Acts surprised when she starts to mimic a voice. No one suspects anything and regards this as something neat/cool/unique that Mimic's done during her stay
- May or may not slowly start to frame the target dragon, making them look like the aggressor towards her? Basically tries to get clan to turn on them
- When target is at their lowest, its easiest for her to "take their existence." Probably takes their soul and consumes it and then masquerades as them in the clan for a bit before eventually deciding to leave the clan under the guise of the original dragon wanting to travel the world.
