Masema Dagar is a character in the Wheel of Time fantasy series by Robert Jordan. He was a soldier from Shienar who fought in the Aiel War, where he developed a strong hatred for the Aiel. This animosity is apparent even twenty years after the war ended. In The Great Hunt he followed Rand al'Thor in the chase for the Horn of Valere, which was discovered in the Eye of the World and subsequently stolen by Padan Fain. After seeing Rand wield saidin he swears to fight for the Dragon Reborn and becomes one of his most fanatical supporters.
After being sent down out of the Mountains of Mist, along with other Shienaran soldiers, in search of an elderly women in Ghealdan by Moiraine, he styles himself The Prophet of the Dragon and heads a quasi-anti-establishment social order in the western regions of Randland, with the ostensible purpose of gathering followers in support of the Dragon Reborn. His "army" has ravaged and pillaged the countryside in Ghealdan, a country in the Wheel of Time, killing and burning in the name of the Dragon Reborn. His former career as a soldier has helped him as a leader although most of his followers are not soldiers, as they seem to rely far more on numbers and fanaticism than discipline and skill.
Perrin Aybara was sent by Rand al'Thor to stop Masema's armies from their pillaging. Masema agreed to accompany Perrin back to Cairhien where Rand was expected to be, though both appeared untrusting of the other. These plans were halted when Perrin's wife was kidnapped by the Shaido Aiel. Masema agreed to accompany Perrin to rescue his wife Faile. It is implied that Masema forged an agreement with the Seanchan, although the terms of the agreement were not revealed.
In the battle of Malden he and his army fought the Shaido Aiel. Many Shaido warriors focused their attacks on Masema's army, whose position was not as well defended as the Two Rivers bowmen. During the battle, Aram attacked Perrin. Masema had convinced the former Tuatha'an that Perrin was Shadowspawn. Although the Shaido were defeated and their captives, including Faile, were rescued, only a small remnant of his army survived. Masema fled with them. Perrin's followers and the Seanchan were able to kill or capture the Shaido that did not flee. The prologue to The Gathering Storm reveals that after the battle of Malden, Faile ambushed and killed Masema and his surviving followers.
