The Order of Ascension are a group of former Guthixians based in the Monastery of Ascension, found beneath the Feldip Hills. The order base its beliefs on Guthix's principles, founded and made to fight against the gods. But after the god's death, the order lost its path and have since begun experimenting on local villagers in order to create a new god to worship.
The Order of Ascension most commonly refer to the six legiones who lead the Order. These six legiones are powerful mages using magic learned from Guthix. They use this magic to experiment on villagers kidnapped from local villages in order to try to "recreate" Guthix despite his wishes and the wishes of the Guardians of Guthix, specifically Ocellus Virius, the Guardian outside of the monastery.
