Her name is a morph of the Finnish Goddess of the forest and hunt, Mielikki.
Mia's Finnish Goddess counterpart is said to have been responsible for the creation of bears; Mia herself being a warden can summon a bear companion, and also has a bear as a mount.
Mia once loudly threatened to eat another warden's summon, because it was standing on the crafting deposit boxes.
One time Mia was having a conversation with someone about a topic they both felt heated about, when she abruptly told a passerby to "shut the F* up" because they happened to comment on the topic, but weren't part of the discussion.
