A goddess, and one of the Lords of Judgment.
Nyssa typically manifests as a dim shape floating in the air.
Sending The Necromancer to aid Sethra Lavode during the restoration of the Empire was strongly supported by Nyssa.
Nyssa originally opposed allowing Zerika to leave the Paths of the Dead with the Orb, but later changed her mind when she became impressed by the Phoenix.
Nyssa also aided the Lords of Judgment in defending the Lesser Sea of Chaos from an attack by the Jenoine.
