Castor goes to Moreal Princeps, capital of the Moeral sub, gateway to the Median Hegemony, heart of the Final sector. This is the location of Asmodeus' forward base. You came here after Nim-Kor to pay tribute - and to secure supplies and repairs for your ships.

You came away with much more: A deal with Asmodeus that eliminated the troublesome Obel Gar and made you the undisputed Apostle of the 10th Host, a very nice battle barege included. Plus your supplies, including a few hundred suits of power armour made from the armoured glass mined from the surface of Moreal Princeps.

All in all a pretty great way of offering tribute!

Thus ended Chapter 1 - Raiders of the Deep
