Kassis Esslik presents five Vass for your scrutiny to join the crew. Two are able seamen.
Plissa, a rogue by trade and the first female Vass to be part of the crew. Female Vass are not commonly seen at sea on ship, or by non-Vass. Usually, they just are recolonized as such. Their scales are smoother and more rounded and the are overall smaller in size.
The second is Fessiz, a massive Vass fighter that rivals Thermon is size (but not quite).
