lasts 1 million years

The volcano Lh'arna is silent, the world of Lharna is barren and blighted. Magic residue and waste (from the giants and the dragons) has contaminated most of the known world and the undead feed and multiply in dark and hidden places. But the fairies, tiniest of the sentient beings, emerge from the cracks in the broken land and take it upon themselves to rebuild the world. Fairies toil long and hard to create a land of unspoiled forests and open plains. Lharna becomes a fairy garden.
Instead of enslaving the other races (like Giants) or warring (like Dragons) the fairies freely share their wealth with elves, dwarves, orcs,
goblins and gnolls. During this time of plenty, all peoples co-exist in relative peace. But the overuse of magic allows a great force to storm Lharna from the Netherworld. While the undead tempest rumbles on the horizon non-fairies squabble over territory. In defense of Lharna, fairies must face down a terrible undead force. The fairies win the battle, but because---other than a few elves---their allies do not support the cause, the fairies pay a terrible price. Fairy casualties are staggering.

While they win the battle, the fairies cannot hope to win the war alone. The undead assault from the Netherworld is relentless and unending. The fairies have no choice but to conjure up an enemy so powerful and insidious that it will destroy the undead.Auberon the Dreamer---a might fairy sorceress---casts a spell called tremendous reality altering spell she calls the
Androclysm. Most of the remaining fairies depart the world of Lharna, vowing to remain in the hidden plane of Fairyland, only to return after the Androclysm as washed Lharna.
