[Spoilers C4E4] The Mystery of the Stronghold in Gormolay

We know that as a price for his betrayal Casamir was awarded lots of money and a deed to a Stronghold to Gormolay.

What would Casamir want with this Stronghold?

To make things interesting, we know that when Cyd saw Casamr with the deed, he snatched it and ran off with it.

Why would Cyd want the deed.?

We know the Halovar have holdings in Gormolay, We know they are shipping Filament here.

Could there be a connection?

Any theories?
