Katarina "Katya" Martikov is a Wereraven  and a member of the Keepers of the Feather. A young adult, Katya is not yet married, and lives with her father Adrian Martikov at the Wizard of Wines winery. Kat is a bold adventurer and fighter. She is an active member of the rebel Movement, helping on many missions around the valley.

Katya's mother, Muriel Martikov, was presumed to be dead for years, but was recently discovered to have been imprisoned by Baba Lysaga in her creeping hut.

When the party asks about the dangers of Berez , Katya volunteered that Baba Lysaga lived there. She then recited a poem, with Ireena joining in:

She takes little girls and bathes in their blood,
She takes little boys who don’t do as they should.
She lives in a house that walks on two legs,
She keeps many toads that sit on hen eggs.
In the skull of a giant, she flies through the air,
She comes for bad children, so you better beware.
