when I realized swamp wickerbeasts can have belly scales, I jumped at the opportunity to design an alternate version of Omen where they are one because wickerbeasts are good. and I needed to treat myself.

This version of Omen isn't a shapeshifter or anything special, since wickerbeasts aren't and can't use magic. They just lurk in a gloomy swamp alone because they're too feral for the city, and too city-ish for non-city wickers. Just a horrible little limbo of isolation.
They hate people trespassing in their swamp.
