Red-haired planeswalker

The red-haired planeswalker, so-called for her long red hair that she wears up, is a Human Planeswalker. She sports glowing chartreuse tattoos on her arms and wields three jagged swords and one straight sword. She dresses in leather and cloth. On her cloth chest piece are scarlet and chartreuse stones and a complex design which features a large chartreuse stone that forms the iris of a human eye. She uses green magic to summon saprolings and elementals. She was believed by Darigaaz to hail from Urborg.

Ravnica and the Meditation Realm
The red-haired planeswalker eavesdropped on a conversation between Ral Zarek and his guildmaster Niv-Mizzet. She gathered information about an aetheric lens that she stole (either before or after the conversation), and then fled the plane. Later, she ambushed Ral on the Meditation Plane and flaunted her success. When the Magic: Legends planeswalker arrived, Ral became temporarily distracted, just long enough for her to attack him and escape, leaving several swarms of saprolings and other green elementals to plague him there.

Zendikar
The red-haired planeswalker fled to the Floating Isles in Tazeem, where she met with Noyan Dar. She showed him several artifacts she had stolen from other planes, claiming they would help him restart the Roil that had calmed following the recent defeat of the Eldrazi titans. Not believing she could have brought them from other worlds, he turned her away; he would find some other way to restart it.

Next, she visited Thada Adel, who eagerly embraced the opportunity to blackmail her rival Noyan Dar as unwilling to help heal Tazeem. In exchange for the foreign artifacts, which included Ral's aetheric lens, the red-haired planeswalker left Zendikar with the Khalni Seed.

Further exploits
The red-haired planeswalker busied herself with stealing objects from other locations as well, though the sequence in which she did so is uncertain:

Gavony
Upon her arrival in the village of Hexenrast, Ulav led her to his mentor Nani Oulav, the witch of the Moorlands. She offered an apprenticeship to the planeswalker and tasked her with retrieving the body of Geralf Cecani's masterpiece, previously rendered inert by the Magic: Legends planeswalker, another of her apprentices. Realizing its potential value on other worlds, she took the body instead of delivering it to Nani.

Shiv
On the continent of Shiv, she bargained with Lord Gavon Deniz in his plan to capture and activate the Mana Rig. While Deniz used one of her curiosities to bind Darigaaz, she used another to control Keltaz of the dragon brood of Kyashatar, causing Keltaz to kill several Benalish soldiers. She also killed Squee and several other goblins by summoning a swarm of saprolings, not realizing Squee would rise again and tell the story. Her motive for helping Deniz in Shiv is thus far unknown.

Tolaria Academy West
Deep within the caverns of the Crescent Shores of Tolaria West, the red-haired planeswalker swiped a cerebral matrix that the geomancer Khalila of the Society of Mishra was using to control the minds of prospective Tolarian Academy students.
