[@mechOrigins] I think this is a good idea, the guardians things. But the fact that their death results in such devastation is what nags me. I like the idea of Dwarves living above a giant molten giant, that holds the ground up beneath them in its slumber, and the Long Leaf Tree of the elves, much like a LOTR Ent, but much larger, it moves very slowly around its lands, but when provoked it will unleash wooden hell. 

Maybe their deaths have different impacts?
