Is there any more background on D'roi and Lahaven?

How would you equip them? Lets say you use D'roi as a Lord and Lahaven as a hero. Bow of the seafarer and the thing that makes his and his units all attacks magic to D'roi and Blade of sea gold to Lahaven maybe?
And how would you suggest an army led by them? Maybe only lothern seaguard and shadow warriors (As seaguard rangers like in the SoC lothern army list)? And some DoW and Regiments of Renown maybe? Lumpin* maybe?

And could a list like this actually be good/competitive/fun?

* Lumpin and D'roi?! I smell sitcom!
