The Underdark Uprising

Mystra, the goddess of arcane magic died and Lolth, Demon Queen of Spiders began making her bid to seize control. She used her following to grow an army for her, she had churches popping up all over Toulon the most notable one being in Aderloth. Lolth wanted everlasting darkness to the surface world so she could have the drown be the only race left standing.
The war began days after the fall of the owls at the gates of the underdark. Droves of Drows, dragons and worms flodded the streets of aderloth. The ground began to shake and the sky blacken as Lolth stepped on the ground of Aderloth. Pure chaos began to ensue Lolth sent her armys all over Toulon, they invaded Aderloth, The Bronze Lands, Rosnoku.
All the kingdoms she attacked where left in ruin, the factions of Aderloth fell apart. With only a few remaining.
Little did Lolth know but her Son Vhaeraun had been working in the shadows to stop her. He used his followers, the people of aderloth and of course the help of the Forgotten to put a stop to her.
Vhaeraun had been searching for a legendary spider pendant that was said to be able to trap any god. He used the Forgotten to find it for him, little did they know what they had discovered.
The Forgotten followed Lolth to every location she attacked until they finally tracked her down and proceeded to trapped her. The Forgotten had to fight her until she was weak enough to use the spider shaped pendant they found in the underdark to capture her.
