What do you think about incorporating some of the creatures from Starcraft like protoss or zerg in a strictly adventurous campaign with non-blooded PC's? Of course, all of the protoss tech would be unavailable, but their wisdom based special abilities could balance them. As for what are they doing in a world cut off from the universe by the shadow world, they just came before it split off from Aebrynis! Hybernation for protoss(they are immortal, after all) and for the zerg, well frozen in ice, perhapse? Any ideas?
