For those of you not familiar with the deep lore behind Dungeons & Dragons, Neverwinter is here to fill you in with everything you want to know about the Illithid. Sure, you might have thought they were just random squid-faced weirdos hanging out in the darkness, but it turns out they’re star-faring monsters with a desire to rule over entire planes of existence for alien and barely knowable goals along with a propensity for eating brains. So it’s actually a lot worse than just squid-faced weirdos!
Equally bad is that one of the races that was long a victim of the Illithid predations wound up splitting into two factions, and one of those factions, the Githyanki, have decided that the best way to own their former tormentors is to do the exact same thing as the Illithid do. Thus, players will need to entreat the ascetic Githzerai to help them get into the middle of the endless war between Githyanki and Illithid raging in the Undermountain. This is probably fine. It’s all part of the leadup to the next major update launch, which does tie into many of these concepts.Source: Official Site
