We need help with creating a campaign.

The campaign is nearing its end: Vel'iar and Khorgiat (the name of the Orc hero) set off east, to where several clans of Orcs who worship demons reside. But along the way, they encounter "good" Orcs who attack them, an Order detachment catches up to them, and troops are sent from Shio to eliminate the threat posed by Vel'iar. (Here is a large map, 2x1x1).
