Glimmering Isles: When Worlds Collide
Having discovered remnants of ancient magic, the Orcs, united under their prophet, gathered the other barbaric races to wage war against the surface races. It was not until races performed together according to their strengths, be it dwarven hardiness, elven tradition, gnome ingenuity, or halfling resourcefulness.
The war waged on for 47 years before the surface dwellers emerged victorious. The remaining savage races fled deep into the mountains where the dwarves and gnomes worked together to collapsed tunnels on them. The day the orcish prophet was slain marks the beginning of what the elves call the Third Era. It has been almost 400 years since this event, with the first year of the campaign occuring on 386 TE.
