Priestess Zul-Gwenwynig is an elf who rows the boat to Zulrah's shrine in order to offer sacrifices. She will allow players to use her boat after they speak to High Priestess Zul-Harcinqa, replacing the original sacrifice.
Should a player die during their battle with Zulrah, when speaking with her again, she will give back most of the items the player lost in their encounter with Zulrah. Some items such as the Lunar staff can not be recovered. If they die a second time anywhere without reclaiming the items she is holding for the player, they will be permanently lost, unless the death occurs within a minigame deemed safe, such as Pest Control.
If the player manages to kill Zulrah in the encounter, the player may speak of it to Zul-Gwenwynig. She will respond that Zulrah cannot die so easily from their weak attacks and tells them to return to see what Zulrah has in store for them.
