The temple was once part of the capital of the Zarosian Empire, Senntisten. After Zamorak banished Zaros, the temple, along with rest of the capital, was overrun by Zamorak forces. The remains of the city were only recently uncovered. During the quest, an adventurer assisted Azzanadra in retrieving the Frostenhorn, Barrows icon, and the Relic previously stolen from Entrana. With all the relics in place, the temple is restored and Azzanadra can again communicate with Zaros. It seems that the portal links Zaros to Gielinor.
