House Velahr - Locations
"...they decided to draw their Household into the planes, protected from outside assaults. Thus on the night of the blood moon, the zenith of Innoruuk's divine powers, that occurs once a millenia, the three began their work. They had spent months in preparation, further shaping the complex into their desired interpretation. Now, all was set in place.
Sitting upon the top of the complex, which would also become known as Duk Gaaroth as it was before, they amassed their strength, focusing on opening a breach within the planes, a tear in the very fabric of the world. Nightmares came at them, horrors unknown to the people of Norrath, trying to break their concentration, but they would be undaunted. Slowly their stronghold was drawn into the void intact, breaking away from the confines of Norrath's place in the realms and it was thus that it was drawn into the plane of Chaos, a realm between the planes of Hate and Fear, where even the strongest of heroes did not venture, but these of three of the surviving nobles had been successful. As they passed their minions began to erect the portal that would serve as the door to their now protected home. The home of House Velahr."
