Malaeragoth enjoyed solitude, usually walking slowly in the tunnels of his home and murmuring to himself his thoughts, comments, and unfolding schemes. For an unknown reason, he payed attention to news about Sembia and the Cult of the Dragon. Thanks to many scrying mirrors, he could spy outside his realm and on the surface.
Malaeragoth had a lair called the Realm of Stone and Shadow. It was divided into many chambers with various uses: one for example was full of water, and another housed many sparkling magical gems called beljurils. He had several skeletons and zombies at his service for his needs.
