At the dawn of the Age of Darkness, Tenebrae Cathedral was a shining point of light in a sea of death and despair. As the Jihad raged about it, Tenebrae was protected by the Goddess Everen and escaped much of the bloodshed that was beginning to sweep across the land. But then, in a bold and calculating move, Karaveth was able to distract the goddess for just an instant. But an instant was all that was needed for a follower of Karaveth was able to infiltrate the Cathedral and strike at the heart of its power and cast a curse of eternal darkness on the city. As the light deserted Tenebrae, all manner of undesirables moved in. And what was once the shining light of Tsunami has now become a cess pool of evil. Many attempts have been made to reclaim the cathedral for Everen, but evil's foothold in that land of darkness is too strong. Should you wish to test your strength against the dark forces entrenched there, I believe that Tenebrae was located somewhere to the northwest of the Plains of Yaresh, in Thyrkon.
