You need to add the correct semantic tag to the region which is your capital. The wiki will then be able to automatically find it and use it where appropriate. I believe the correct tag is [[capital of::Fallangard]].
The problem here the realm is listed as lost, and the region is listed as belonging to Caligus. If this is not the case I can update the wiki but like I said, I don't play on the continent so I know nothing about its current state.
