Quest-Related EventsEdit

After you have disrupted the harrowstorm ritual which was targeting the nearby Dusktown, Sister Tharda will flee with Pentarch Khorb to the ruins. You, Lyris and Fennorian will need to enter Kagnthamz to hunt them down.
Once you have killed Khorb who assassinated Queen Gerhyld, Tharda can be found down the passage in a large open chamber. However, when you reach her she will not be alone.

Fennorian: "You listen in. I'll unlock the door."
"Rise exarch and be reborn!"

While he picks the door's lock, Lyris will go over to the opening to watch the scene below. Sister Tharda and an unknown man stand before a stone construct with a large urn between her and it.

<As she performs the ritual a blue Reach sigil forms beneath her.>
Sister Tharda: "Rise exarch and be reborn!"
<The construct goes one knee and blue lights from the urn enter it.>
<A wolf howls is heard.>
<The stone construct shatters and a Werewolf Behemoth emerges from it.>
Exarch Ulfra: "Tzinghalis? Where is this place?"
<The man walks towards the werewolf.>
Exarch Tzinghalis:"The Ashen Lord commands it, and so we live once more, Ulfra."
Exarch Ulfra: "Alive again? How?"
Sister Tharda: "You have the Icereach Coven to thank for that, werewolf."
<Tzinghalis jabs his finger at her.>
Exarch Tzinghalis: "Using my recipes, witch."
Sister Tharda: "I meant no disrespect, Exarch Tzinghalis."
<Ulfra starts sniffing the air.>
Exarch Ulfra: "We're being watched, brother."
Exarch Tzinghalis: "Next time, Tharda, the Ashen Lord will expect more than the restoration of a single reliquary. Now deal with the intruders or I'll toss you to the harrowfiends."
<Exarches Tzinghalis and Ulfra leave the chamber.>
Sister Tharda: "Come out, little skeevers. Come out and play with Sister Tharda!"
Lyris Titanborn: "How many of your sisters am I going to have to kill before you give up?"

You can then head downstairs to face Sister Tharda, she cry vengeance once she sees you.

Sister Tharda: "Is it you who's killed my dear sisters? Our vengeance will plague you beyond the grave!"
Sister Tharda: "You cost us a great harvest. Perhaps your souls will suffice?"
Sister Tharda: "These stone husks would have all bore fruit if not for your interference!"
Sister Tharda: "You think to kill me? The Ashen Lord will see us all reborn!"
