A Servant of Death

A Servant of Death is a side quest in.

It is connected to the Council of Stars and Court of the Penitents main quests.

Synopsis
Berath tires of mortals evading the natural cycle of death and rebirth. They showed the Watcher two individuals in particular - a dwarven man and an elven woman - who have extended their lives for centuries. The message is simple: These two individuals have cheated death for too long. Ending their lives would no doubt please Berath.

Walkthrough
You get this quest from praying to Berath during Council of Stars. She asks you to assassinate two specific individuals:

Archdruid Rehstin
 * In the north part of Elms' Reach, there's a cave called the Blood Sands. Inside, there's a bunch of dwarves dressed in red calling themselves the Ethik Nôl.  Their leader is Archdruid Rehstin.
 * Pull what information you want from him and then kill him (before or after the sacrifice – your choice). Everyone in Blood Sands (except for Keeper Wrdha) will turn hostile if you do this, so be prepared. You will earn Extraordinary reputation decrease with Ethik Nôl, Major decrease with The Fangs and Extraordinary increase with Ovates for killing the archdruid. Killing other cult members give major decrease with Ethik Nôl.

High Ovate Erona
 * Optionally talk to Iswld at the Golden Grove headquarters in Elms' Reach, who will tell you that the High Ovate is on a retreat in Elmshore.
 * Travel to Elmshore, and find High Ovate Erona with some of her followers on an island on the far right, middle of the map. This little island can only be reached from its southwest corner. You have a couple of options:
 * Attack and kill her, resulting in a Major reputation decrease with Ovates of the Golden Groves.
 * If you pass the Resolve check (15 Resolve) she will accept her errors and she will kill herself without a fight by turning to stone and will earn you a Major reputation increase with Ovates of the Golden Groves.
 * Either will earn a Major reputation increase with Ethik Nôl.

Finally return to Berath at Teir Evron. You can basically say whatever you want and the quest will conclude.
