Nybeth appears as a withered corpse, dressed in tattered robes with the remnants of a red headband wrapped around his head. Despite his decrepit state, he still has a white mustache and beard.
Nybeth Obdilord was a powerful necromancer and lich on another world, obsessed with overcoming death and resurrecting the dead. Traveling to Hydaelyn through unknown means, he set up base in the Palace of the Dead, within the Black Shroud, where he continued his dark experiments on raising the dead. After numerous failures, he chose Edda as his next test subject, believing that her strong soul would be ideal for his work. Although he was successful in partially resurrecting her, he was unsatisfied by her condition and puzzled why her soul seemed to be yearning to pass on, not understanding why anyone would willingly choose death.
When the Adventurer entered the Palace of the Dead, Nybeth sensed that Edda's soul was connected to them in some way, and sent her to confront them as a test. The Adventurer was able to defeat Edda on the 50th floor of the Palace, freeing her soul, and eventually confronted Nybeth himself on the 100th floor. Nybeth engaged the Adventurer in battle, but was defeated. He questioned the Adventurers motives, insisting that everyone should appreciate his efforts to beat death, before dissipating.
After Nybeth's defeat, the Adventurer was shown some writing, believed to have been written by Nybeth. However, as Nybeth came from a different world, the language he used was entirely unknown in Eorzea. Using the Echo, the Adventurer was able to use the papers to see brief glimpses of Nybeth's past, including his apparent motive to resurrect his dead love.
Nybeth serves as the final boss of the Palace of the Dead storyline, and is fought on the 100th floor of the dungeon. During combat, he can cast powerful spells, as well as summon undead creatures as adds.
- Nybeth originates from the game Tactics Ogre: Let Us Cling Together. A villainous necromancer, he is fought several times by that game's protagonist. He eventually transforms himself into a lich and is confronted once more in that world's version of the Palace of the Dead, where he is seemingly defeated. His appearance in Final Fantasy XIV would imply that he survived this battle, however, and found a means to travel to Hydaelyn.
