The Nether Path was a secret tunnel created by the great archmage Fistandantilus under the Tower of High Sorcery at Wayreth. This tunnel had a hidden cave located in the Wayreth Forest, and it led from that cave into the Tower. Once the cave was found, it would only be open for a limited time before the forest would move again and it would close.
