Wrenn

Wrenn is a dryad planeswalker introduced in Modern Horizons. Her homeplane and lifetime are unknown, but it is speculated that she lives in current times.

Appearance and Characteristics
Wrenn is a white-haired Dryad who can symbiotically bind with and pilot a Treefolk. Her current host is her sixth. Wrenn doesn't name her symbionts, so the current host is simply known as "Six".

Without Wrenn, Six can't planeswalk. Usually living organic material can't be brought along on a planeswalk. In this aspect, Wrenn breaks the rule in a way similar to Yanggu planeswalking with Mowu.

Dryads are typically associated with trees, but it is currently unknown if Wrenn binding a treefolk is necessary for her survival or for another reason.
