You studied Necromancy because it was interesting and hired Orchish mercenaries because they were fierce in battle and worked cheap.
Now your domain is in open revolt and the Elves are landing soldiers on your shores. Most of the garrison of the city of Wind has deserted, all that is left are the Orcs that will not surrender to the Elves.
Only the Codex of Necromancy and the secrets hidden in the Underworld can offer you any hope of defeating your enemies. There are two paths to the the Underworld; one at the head of the river and the other to the South-East of Saddle.
(This is the first map of a new campaign following the career of the Necromancer Soulclaw).
