Arasta of the Endless Web

A Victim of the gods' petty rivalries, Arasta was once one of Nylea's most beloved dryad companions. Phenax's bitterness saw her transformed into an arachnid Monstrosity and driven into the darkest depths of the Nessian Wood. Now she broods on her unjust fate and the fickleness of the gods who left her Cursed with monstrous immortality. Arasta appears as a gigantic spiderlike creature, her few Humanoid features made monstrous by cruel magic and ages of Hatred. Webs fill her lair deep in the Nessian Wood, sticky strands made not of silk but of her own endless hair. In her darkened realm, Arasta broods on her Hatred of the gods and their servants. She doesn't do so alone, though, as innumerable arachnids fawn over her, serving as her eyes throughout the Wilderness, disposing of victims trapped within her hair, and sacrificing themselves in her Defense if they must.
Arasta lives in an enormous, gnarled olive tree called Enorasi, which was planted millennia ago by Klothys. It is said that those who eat of its fruit can see glimpses of the future. Eating the fruit brings with it a risk, though, for those who Klothys finds unworthy might be driven mad. There, within Enorasi's hollow trunk, Arasta awaits the next would-be Prophet to make her meal. Her webs stretch beyond the branches of the tree and carpet the Forest floor of her realm.
Tales are told of Forlorn souls who, because of grief or Madness over the loss of a loved one, have sought out Arasta's lair, as it is rumored that some of the strands of her web are anchored near the edge of The Underworld and can enable a Traveler to reach that realm's ashen shores. But those who enter her domain unbidden almost never go unnoticed, for Arasta can sense the slightest vibration along her web hair, and her children act as spies on her behalf.
