Umar was spawned in the Faltine Dimension by Sinifer, a Faltine. The Faltine are beings of pure magical energy that exist in their own universe. It's implied that normally when Faltine spawn, that the new beings are exact copies of the previous, but in this instance, the spawn were different. Unlike Sinifer, they craved physical matter. When Sinifer tried to stop them, they transmuted him from energy into matter, essentially killing him. This angered the rest of the Faltine, and so Dormammu and Umar were exiled from the dimension of the Faltine.
The two fugitive Faltine then entered a universe known as the Dark Dimension, which was inhabited by sorcerers known as the Mhuruuks. Their ruler Olnar dreamed of returning to the days of warfare and conquest. Umar and Dormammu befriended Olnar and played upon these desires. They showed Olnar how to make conquest of other dimensions and bond them with his own. Olnar greedily subjugated several dimensions and added them to his own domain. In time, the rogue Faltines led Olnar to shatter the barrier between his dimension and that of the Mindless Ones. The Mindless Ones were a horde of soulless brutes that exist simply to destroy anything that lies in their path. The Mhuruuks were beaten back by the onslaught and many were slain, including Olnar. Dormammu and Umar then slew or exiled any wizards that might oppose them. Then they barred the Mindless Ones behind a great mystical barrier.

This battle weakened Umar, and she became subordinate to her brother. Dormammu ascended the throne as regent and ruler of the Dark Dimension. He reassumed his Faltinian form of flame, but Umar chose to remain in her human form.
Umar has a gifted intellect, and vast knowledge of magical lore. She has tremendous ability to manipulate the forces of magic for a variety of effects, including inter-dimensional teleportation, size transformations, time travel, transmutations, energy manifestations such as powerful concussive blasts, magically constructed animate beings, telepathy, illusion-casting, limited mind-control, etc.

As ruler of the Dark Dimension, Umar's head was surrounded by a plume of mystic fire, the flames of regency.
