Dominion of the Dead
A kingdom in the North, once ruled by the revered King Fergand. Fergand was killed when the capital Mordan collapsed (an after-shock of the eruption of Mount Sker in Naxt). His nobles fought over the throne throughout the Darkness, and the conflicts weren’t resolved until Gwyon the Great established the Empire.
The Kingdom of Rhyl used to have sovereignty over the Northern Marches, while letting settlers take care of their own affairs. Gwyon made a separate peace with the Northern Militia, leaving the Northern Marches outside the Duchy of Rhyl. Today the duchy’s boundaries are the River Wyv and the River Alna, as well as Lake Ryhl (from which the old kingdom got its name).
