Galla

You're more likely to hear a chuckle out of Galla than a sentence. She is extremely prone to nervous giggling, and given she has both social anxiety and a dark sense of humor, that makes for a lot of laughter.

She spends most of her time in the company of Albi, who despite his morbid, monotonous tendencies has developed a keen rapport with her. They are often found roaming the forest, chuckling over some shared in-joke or working on their natural history journals. Her freezing breath is useful for preserving specimens, and Galla appreciates having someone she doesn't feel she needs to explain her laughter to. (Albi, not the most socially aware dragon himself, reckons black humor is a Mirror dragon thing, especially since his other major Mirror acquaintance is Caoradhromain.)

If you need a translator for the strange Fae, Galla is your best bet.... provided you're patient and accepting of her quirks.
