Stygian Crypts and Shining Heroes
King Skalmad (Deceased?)
Skalmad is the troll king in P1 Trollhaunt
Skalmad is the self-proclaimed king of all trolls. It is rumored that he commands terrible magics and that he possesses an enchanted eye.
The adventurers encountered and killed Skalmad in the troll foundry found in the heart of The Great Warren. As he died, he taunted the adventurers with word that an assault force was heading for Moonstair. Afterword, his body was consumed by a fire originating from his enchanted eye.
Upon their return to Moonstair the adventurers discovered that Skalmad used fey magic to gain power, and that this magic might allow him to return to life.
So, the adventurers trekked into The Great Warren, and succeeded in defeating him yet again.
What they did not find was the source of his power. Instead, they discovered that his throne was a magical passage into the feywild.
