Vivend

Vivend was known (the years before and after the bloodmist) as Wyrmland. It lies north of the Landa line, and were never settled by the early Eilanders.

My personal take, is that the Wyrm church holds a somewhat low profile and reside mostly in the north-eastern parts of Ravenland in Vivend and northern Margelda. [...] The Rust church might have tolerated them since the Wyrm adherents could provide some needed materials and knowledge.

In Alderland, the Wyrm church and the Rust church have coexisted for a long time, although things currently are deteriorating towards civil war. They might traditionally accept each other.
