Awakening of iron.

The precursors were the most advanced civilization in Terras history. they were the only ones that had fully autonomous machines, and even the advanced dwarves can't produce machines that work on their own. the precursor machines were able to blast beams of light capable of incinerating a man. however, the precursors were an atrocious society. they would abduct people from all around Terra, taking wildlife, and even decimating an entire other civilization. The elves with their intense pride in their creations were captured, and turned into horrid abominations known as the twisted, true elves seeming to remain only in the dryads. the mighty dragons with their almost indestructible hide and scales would be captured to almost to the point of extinction. the gods themselves, weak from pouring their life essence into terra, created their last races to defend their planes from their assaults.. then they seemed to dissapear, without a trace. their facilities lay dormant all over the world, machines embedded in rock or dirt sleep.. until now. the machines and facilities are waking up, and nobody is sure how or why. it is up to you to figure it out, and stop it, lest the precursors be back.
