The Drow discover Magic.

Metaphysical / Paranormal event

The first wizards appear on Meaghana.

After they were driven below ground Alisana decided that to protect her people they would need to investigate the caverns they had made their home. During one of these expeditions Alisana came across an odd symbol entombed in the ground. Little did she know that this was the elder sign of Possibility. Her innate Fae-given powers activated the Sign and thus magic was born on Meaghana. The power exploded and filtered out of the caverns to form the weave. Those that come into contact with it became the first Wizards.
