Neverwinter Nights: Hordes of the Underdark is the second official expansion pack for Neverwinter Nights, a cRPG set in the well-known Forgotten Realms. The add-on offers a completely new campaign in which the players have to save Waterdeep from the ancient evil. The action of Hordes of the Underdark starts when the eponymous hordes of vile creatures and monsters from the world underneath (including beholders, dark elves, grey dwarves called duergars and mind-flyers called the Illithid) led by a mysterious and charismatic drow (dark elf) attack Waterdeep. This army is so powerful that the defenders are doomed to fall. The only thing that can save Waterdeep is uncovering what caused the alliance of the otherwise sworn enemies, and making sure that this alliance is dissolved.
Hordes of the Underdark is an add-on meant for high-level characters. The developers suggests to play with a 15th level hero or even a mightier one. It’s also possible to transfer your character from the original campaign of Neverwinter Nights or the Shadows of Undrentide expansion, or make use of the built-in creator. The expansion is designed in such a way, that it allows for character development up to level 40 (the previous level cap was 20th level).
