When I entered the great hall of the Wavebreaker Keep on an island in the Padomaic Ocean, I was greeted by its occupants, a Necromancer named Reynard Valtienne and his wife Sabine, a Lich. Oddly enough the couple seems friendly.
Dead Shores
In the prisons of Wavebreaker Keep I found Relam Indoran and the body of his sister. He described the horrors they had been through, and asked me to retrieve his sister's armor and weapon, so that he could use it to help me defeat the necromancers.
When I touched the body of Dilavesa Indoran, she was reanimated and attacked me, possessed by mindless bloodlust. I had no choice but to strike down the abomination that she had become. Relam seems even more distressed than he was before.
I was able to talk some sense back into Relam, and he is now ready to join me in confronting the necromancers. He asked me to tell his superiors in Almalexia of his sister's, and should he not survive, his own demise.
The necromancers of Wavebreaker Keep are dead.
Relam Indoran thanked me for ending the threat of the necromancers. If I ever visit the city of Almalexia I should see his commander at the Offices of War at the Ordinator stronghold.
