Military action
Dwarves invade Elven lands to acces mithril roumered to be hidden in the northern mountains.
This however leads to the rediscoverment of the orcs who had been living in the mountains after the banishment. The orcs retaliate driving the dwarves back leaving only one stronghold left for the dwarves to defend. The elves manage to keep possession of the nen-taûre forest but not without great loss.
