WWH9 Seidkona [PDF Encounter, World War Horror]

Noway is mostly empty, with destroyed and abandoned towns along the route you are taking toward the ocean. However, after a chance encounter with Jolo's berserkers, you find a young woman calling herself a seidkona (a witch) who wants to join you, but she'll need her supplies that were stashed in an overrun town...

This is compatible with the World War Horror Micro Setting.
