Master Sebrian

Master Sebrian is a character from The New Adventures of He-Man.

Sebrian is the wisest man on Primus, and the most zealous supporter of the Galactic Guardians in the Planetary Council. When He-Man arrives to Primus, he reveals his secret identity to Sebrian, who makes Adam pass as his nephew from the floating city of Levitan.

The New Adventures of He-Man
Master Sebrian was the wise leader of Primus, making decisions about the planet's future in conjunction with the Inner Council. Sebrian was perhaps hundreds of years old, and in his youth, attended the Priman academy with his friend Treylus.

Master Sebrian lived in his home in The Oasis, where he kept a close watch over Caz and Drissi in the absence of their parents. Within Sebrian's home was large library which contained various ancient tomes and magical texts. Sebrian himself was a mysterious figure, who was far more powerful than most suspected; he was able to communicate telepathically, create magical shields to protect himself and could fight hand to hand with his staff if needed. As the shield around Primus weakened under constant attacks from the Mutants of Denebria, Sebrian came to realise that the peace loving Primans would soon be overwhelmed. Looking to the past, Sebrian reviewed ancient legends and discovered "the power of the good and the way of the magic". He ordered the Scientists of Primus to create a time vessel, and sent Captain Hydron and Lieutenant Flipshot to the past to find this power, believing it was the only way to save Primus. Hydron and Flipshot were successful in their mission, bringing He-Man to Primus, but also his arch nemesis, Skeletor.

Following his arrival, He-Man revealed to Sebrian his true identity as Adam, Prince of Eternia, but warned Sebrian that Skeletor was powerful enough to defeat him in this form. Sebrian decided that while on Primus, Adam would pose as his nephew and live in his home, with the cover story that he was a trader from Levitan.

Master Sebrian acted as a mentor to He-Man, often offering sage advice and counsel before He-Man departed on a mission. Other than He-Man, Sebrian was the only person on Primus who was able to communicate with the Sorceress of Castle Grayskull via telepathy, with the Sorceress even managing to reach out across time and help Sebrian on one occasion when he battled evil duplicates of the Inner Council. Eager to forge a lasting peace with the Mutants, Sebrian was fooled by Flogg's false offer of peace and accepted his peace offering of Zeps; seemingly harmless and adorable creatures, which actually transformed into deadly Anadroids and conquered Primus from within. Before the Mutants could reach Onnor, Sebrian gave He-Man the key to the Vasionic Resonator and sent him into the wilderness to form a resistance movement as the Mutants quickly conquered all of Primus and brought it to heal. Sebrian himself allowed himself to be captured, but refused to reveal where He-Man was hiding, even under torture from Skeletor. Sebrian was eventually rescued by He-Man's resistance, and he resumed leadership of the Primans in exile.

When He-Man surrendered himself to Skeletor at Levitan, Sebrian accompanied him, despite the grave risk to them both. As Skeletor prepared to execute He-Man, Sebrian telepathically called Hydron, Flipshot and Mara and signalled them to begin their counter attack, eventually driving the Mutants from the planet and regaining control of the planet. Some time after this, Sebrian was reunited with his old friend Treylus, who referred to him as an "old book worm", and encouraged him to be more adventurous, something Sebrian took to heart as he and Treylus teamed up to rescue the trader's ship from the Mutants. Sebrian would also be reunited with the Priman hero Dukan, whom he know from many years earlier.

Despite Sebrian's hopes for peace, the war against the Mutants continued, eventually coming to a head during an all out assault on Primus while He-Man and most of the Galactic Guardians were detained off world. Sebrian refused to surrender, even as Flogg destroyed many of the planet's defences; and eventually He-Man returned and defeated the Mutants once and for all, forcing Flogg to surrender. Sebrian signed a treaty with Flogg, which was ratified by the Galactic Council, officially ending the war between Primus and Denebria.

Masters of the Universe Classics
Master Sebrian was the wise leader of the planet Primus. He was assisted by his student, Mara.

After the war against the Horde was won, and He-Man returned to Eternia to take the throne; Sebrian was amongst the guests at his coronation.

Later, when the Unnamed One attempted to perform the spell of seperation during the third ultimate battleground, Sebrian was amongst the powerful magic users who attempted to hold back the spell, alongside Teela, Orko, Evil-Lyn and the Goddess.
