Sword of Power (Revelation)

The Sword of Power is a weapon that appears in Masters of the Universe: Revelation.

History
500 years before the time of He-Man, King D'Vann Grayskull and his two young sons were attacked by the Snake Men together with their newfound ally, the Orlax of Primeria.

Grayskull had to forge himself a new weapon, using a special kind of dark ore he obtained from Scare Glow in the realm of Subternia and with the help of Trollan Magesmiths. By merging the newly created sword with his own preternian weapon, he created the Sword of Power that would be used by him and many champions of Eternia to follow. The first of these was Grayskull's son Ro, later to be known as He-Ro and the most recent was He-Man, the most powerful man in the Universe.

The evil Skeletor, who had been trying to learn the secret of Castle Grayskull for years, finally discovered that the castle was merely a shell, and that it's sole purpose was to protect the Orb of Power. The Lord of Destruction used the Shaping Staff to disguise himself and several of his allies and gaining access to the very heart of Grayskull. There he maneuvered He-Man into stabbing him with his mighty sword in such a way that the sword would also penetrate the Orb of Power and open it as if it were a key. Skeletor then struck the orb with his own Havoc Staff, cracking it and releasing the magic power that created Eternia and the very universe. The Sorceress knew that this meant the end of all existence, but was able to freeze time for a short period so that she could confer with He-Man and Teela. He-Man attempted to absorb the magical energy of the Orb with his sword, which split in two. When this happened, his loyal steed Battle Cat transformed back into Cringer and He-Man reverted back to Prince Adam. Skeletor attempted to grab the two halves of the sword for himself, and both he and Adam were obliterated in the explosion caused by the magical impact. The only thing which remained was the top of Skeletor's Havoc Staff.

Without the sword, all magic began to wane from Eternia. The planet itself was dying out, and with it, the rest of the universe would go. Only by calling on the Power of Grayskull could Eternia possibly be saved. Teela reluctantly accepted the challenge to seek out the two halves of the Sword of Power, which had returned to their places of origin: Subternia and Preternia and reforge them with the last remaining ember of magic.
