Rogue warriors of the forest tribes are known to ambush travellers, not to steal wealth but to deter outsiders from entering their domain.

The pious Pen Baedd {buy-th} make their homes amongst the forest. They worship all that is natural and resist the changes creeping into their land.

The mukkelevi is Avallen's most horrific creature. It enslaves its prey so its thralls can search for other victims to join their unhallowed ranks.

Faeseeker for the Faerie Court of Triumphs. Raised on the mountainside, as a boy he strove to join the ranks of the Ever Father. He doesn't have a name yet... Suggestions?

Faeseeker for the Court of Pebbles. She arrived from the Empire and as a fine trickster was welcomed by the Ever Child's tricksy fae. She doesn't have a name... Suggestions?
