Wrenn's History
Wrenn is a dryad planeswalker who can symbiotically bind with a Treefolk. Like all Dryads, she will die without a host after a prolonged period of time. Unlike other dryads, who are born with their respective trees, grow in tandem with them, and never leave them, Wrenn is able to move from tree to tree. Her home plane is unknown at this time.
Wrenn's spark ignited when a forest fire threatened the lives of her sisters. She contained the fire within herself, but at a heavy cost: she'd have to share it (and presumably her planeswalker spark) with a tree or she'd be consumed from the inside. As a dryad, Wrenn needs to be "hosted" to a tree. However, a common tree does not support Wrenn's "flames", requiring a treefolk as a host. After the ignition of her spark, Wrenn found her first (named by her One) host on her homeworld. This made it possible for her to planeswalk through the multiverse.
Respecting her trees' wishes, she cycles through them. Four, Six and Seven have come from Kessig, which planeswalkers claim to have the finest trees in the multiverse. Wrenn agrees, even if she doesn't particularly like Innistrad itself. After she left Six to live out his remaining days as a mighty yet ordinary oak, she began searching for her new host. Following the whispering song of a young sapling, she was intercepted by
Teferi. Teferi sought to learn what the "white witch" was that some residents had seen, and immediately recognized her as another planeswalker.
Due to an encounter with a malevolent entity, Teferi was forced to create a time spell, which was corrupted and led them to walk around in circles. Nearly dying, Wrenn offered to grant insight into metamagic, allowing Teferi to see the spell and undo it. Unknown to him, there was one beneficial effect remaining. Wrenn's sapling had gathered all the time it could contain.
Afterwards, Wrenn met a now fully grown Seven. In gratitude for Teferi's help, she promised him to help undo Zhalfir's situation, but not before showing Seven around the multiverse as the tree requested.
