I'll go with the heavy armored fighter then.

Does Zerul have a military force that they can lend out a small faction of? I could bring my character in with a small group (maybe 3 or 4 guys) of highly trained armored fighters. Sort of like the knight type. From what I could read, the actual army was busy with something else (some sort of royal wedding?). So a small squad could be sent to you guys as help? I'd also control the NPCs, but expect them to die one by one.
