Vuz'lyn has spent a lot of time in the Illithid City laying waste to the endless spawn of illithids and their slaves. Every once in a while he comes across a drow slave, and kills them without hesitation since he knows they are under control of the illithids. Then suddenly, Vuz'lyn gets an idea. He decides to see if his enchantment powers can override the illithid's psionic powers long enough to get some information from the thrall. With a simple casting of Dominate Monster, he brings one under his command and asks it a few questions.
