Eve

Eve is a cat planeswalker from an unknown plane. After being abandoned by her original owners, Eve was adopted by the planeswalker and bounty hunter Kella Rakevan. Kella then took Eve with her as she traveled around the multiverse, until one day, she left for a bounty and never returned. Enraged by being abandoned yet again, Eve's planeswalker spark ignited.

Seeking Kella Rakevan
Within months of being granted the ability to travel between planes, Eve had built connections in the underworlds of several planes. She found lots of information about where Kella had been, but none on where she was or would be. However, she learned from another planeswalker of a being who could provide any knowledge you wished to know. She planeswalked to the plane of Revio, and schemed how she could meet Sethis.

Unfortunately for Eve, the desert terrain of Revio was impossible for a cat to travel long distance. To solve this problem, she decided to bond with a host, the young merchant woman Belle, and hope that her travels would be her ticket out of the city and towards the sanctum of Sethis. As luck would have it, just a few weeks later, as Belle was preparing to leave the city, she encountered the fleeing princess Tara and her friend Reytha, who were also trying to find Sethis. Belle normally wouldn't be the kind to join in on such an adventure, however, Eve persuades her, and the two join them on their quest.

After several weeks of trekking around Revio, the four reached the sanctum of Sethis. The sphinx presented the four with a riddle. As Tara prepared to answer it, Eve telepathically linked with her, and said the answer before the princess could, revealing her sapience in the process. She then asked Sethis for the location of Kella Rakevan, to which he responded: "Belvov." With her job on Revio done, Eve planeswalks away.

Eve on Belvov
On the plane of Belvov, Eve tracks down and kills Kella Rakevan. (This is included in a currently on hiatus set.)

The Tournament of Champions
Five years after the events of Belvov, Eve was summoned, along with Tara, to fight in the Tournament of Champions hosted by Zadan. The two, realizing they cannot hope to win on their own, decide to set aside their differences and team up, since no one there knows Eve's status as a planeswalker. However, despite this, the reluctant partners still lose in the first round to Experiment Zero.

Magic
Eve has the ability to manipulate the people she bonds with to do the things she wants them to do. However, very importantly, this is not active. She doesn't choose to have people do specific things, rather she radiates a passive aura that makes the people around her more likely to align in goals and beliefs with her. It can't make people do things they would never do, rather it can make someone more likely to do something they rarely would do.
