Twilight Temple is a location in Hammerfell seen in The Elder Scrolls Travels: Shadowkey. The First and Second Scrolls of Shadow can be found here. Pergan Asuul makes his first appearances here, and drops the Twilight Shadowkey when defeated, which is needed to complete Witch Tree 3.
The temple contains unique unkillable Zombies, as well as a Shadowgate. Additionally, there are crystals that can be found in the temple that give temporary statistic boosts, and only one can be used at a time.
