Military action
Positioned just outside Omeranth, the forces of Lowvire block the gates, and have a pair of boats manned with a dozen men each blockade the port.
The imperial forces on Reledus don't really have any qualified siege engineers. Thus, they resort to flushing the Velians out via starvation. The Margrave stations Pearl and her army ~10 miles down the road to protect the siege from any Velian activity.
