The leaders of the Cultist Camp have agreed to grant you passage around The Ruins of Welryn and on to the road to The Temple of Eterra if you aid them in a ritual. They’ve told you of two relics they need. One of them is a phylactery storing soul power located under the ruins of the city to the north.
The skeletal figure chained to the device gave you an unusual request to help him end his own life. To do so, you must search the Welryn Undercity to find and destroy the three soul vessels that protect the wards he placed upon himself.
You've completed the Last Imperial's request to destroy his phylacteries, return to him to learn how to end his un-life.
