Succubus Queen Karen
 
Found within the dark depths of the Thorn Cave comes an enemy yet to be defeated. The indomitable Succubus Queen Karen will find her way to Isya in this patch and she will be all but easy to conquer. The Thorn Cave has been opened in this patch and made available only to those who dare venture inside.
 
The current available quest for this content will be made available through a single NPC close to the entrance of Thorn Cave named Bat Hunter Polan.

The entrance of the cave can be found in the northeast area of Alberstol Ruins.

The Story

"Once, the Succubus Queen Karen did not command legions of deadly monsters. Once, she was merely a human girl named Karen. Her family loved her. Her life was peaceful. She was one of the thousands of fairy tale beginnings that dot our world.

Once.

No one knows what tragedy claimed Karen's family, claimed her happy life. We only know that she left the ruins of her life behind, consumed with sorrow and impotent fury. Some legends say that Apoline found her, and granted Karen perfect dominion over all creatures of evil. Others say that the young Karen perfected her magical arts alone, and claimed her own place in the forces of darkness by sheer power. She became the Succubus Queen.

In the end, it doesn't matter what drove poor Karen to darkness. All that matters is that she has occupied the sacred Thorn Cave. She has sent her monsters out to capture innocent elves and men. We have all lost friends, neighbors, family to this monster. This will not stand!

I say we go to Thorn Cave, and drive this creature of evil to her well-deserved grave -- or die trying!"

-Antion, Human Guardian. Final words before venturing into Thorn Cave. Body found half-consumed some months later.

Succubus Karen is going to hit Isya on 3/31/10! She's not going to be an easy fight, though. Her lair, Thorn Cave, is one of the most difficult dungeons we've ever released, packed full of creatures that will challenge even characters at the level cap. Succubus Karen herself holds nearly divine power, and defeating her will take power to match.

But there are rewards for heroes! When Succubus Karen is first defeated, her power will be released and flood the world itself. The first server where a band of heroes defeats the Succubus Queen will enjoy an entire week of bonus Exp for everyone on the server, as Succubus Karen's stolen power is returned to Isya.
