Age of Strife

A time of great war between continents that nearly led to the ruin of the dwarves and the humans, the very near extinction of the Goliath's and the extinction of a Race who's name has either not been recorded or was deliberately erased from recorded history. This age lasted for around three and a half thousand years and very little remains from this time.
Most notably the north part of Estmara was known to have sunken into the sea during this time for reasons not recorded.
This was also the age where the great underground capital of the dwarves "mòr-bhaile mòr" (roughly translates to big fucken city) was destroyed by the mountain it was built under collapsing into it.
