Rat

(when the Religion in Aveyrone page says anything at all about Rat, then this page can redirect :p)

Rat was originally trapped in the Arch with Serpent at the time of the founding of the empire, by some agreement with Dorea. Members of House Rat who lived in the Undercity continued to worship at the under-arch, and they were given shapeshifting abilities by their god.

Rat was released along with Serpent when the two halves of the arch were rejoined, at which point Rat began to grant its followers powers in a vein more similar to the accepted six. Velten du Champ was the first priest of Rat, and eventually became the first Rat Reverend Father and eventually the Patriarch.
