Dharc, Wynn, and Lyna's familiars don't have evolved forms yet, unfortunately. Lyna's familiar is Happy Lover:

Some other facts:
- Lyna is the only Charmer who doesn't have a "Familiar-Possessed" form (yet)
- Dharc and Lyna are the only two Charmers who don't have a "Cataclysmic Charmer" form, either
