26 days until Hellboy Day - Nimue, the Blood Queen
Nimue is a linchpin character in the Hellboy universe, with her arrival and interaction with Hellboy setting the stage for the apparent coming end of the world.
Nimue was a witch in the time of King Arthur, and once the lover of Merlin, whom she betrayed and imprisoned after learning all she could from him. After going mad and worshiping the Ogdru Jahad, the other witches of Britain murdered her. They cut her to bits, sealing her away in a box buried deep in the Earth for 1500 years. Once Hecate fell, when the witches of Britain were looking for a new leader, Gruagach nominated her as Queen, and (very reluctantly) they agreed. Roughly half of all witches drowned themselves before she could unleash her retribution upon them.
Once resurrected, she started to amass an army: “The people out of the dark, those who have lived on dust to sustain them”, with the desire to make the world bleed. She murdered Queen Mab of the fairy folk, dooming their race, as well as ordering the murder of King Uddsvik. Her attacks on Alice and Hellboy lead them to Morgana Le Fay, who showed Hellboy his true lineage, and allowed him to retrieve the sword Excalibur. This caused the noble dead of Britain to raise and follow him to war against her, further setting into monition the fulfillment of prophecies that had been told since before Hellboys birth.
In her final battle, it is revealed the Ogdru Jahad were using her as the vessel to enter this world and cause her body to transform into a Dragon that they could inhabit. Hellboy, choosing to do things his own way, battled her without Excalibur, and was nearly beaten until help form the child Vasilisa. He successfully slew the Dragon, but Nimue’s spirit refused to die alone, and dragged Hellboy to hell with her. Thus far, that is the last we have seen of her on earth or in Hell.
