Changeling

With ever-changing appearances, changelings reside in many societies undetected. Each changeling can supernaturally adopt any face they like. For some changelings, a new face may reveal an aspect of their soul. The first changelings in the multiverse appeared in the Feywild, and the wondrous, mutable essence of that plane lingers in changelings today—even in those who have never set foot in the fey realm. In their true form, changelings appear faded, their features almost devoid of detail. It is rare to see one in that form, for a typical changeling alters their shape the way others might change clothes. However, many changelings develop identities with more depth, crafting a persona complete with history and beliefs to go with each shape. A changeling adventurer might have personas for many situations, including negotiation, investigation, and combat. Multiple changelings can share a persona. Personas can even pass down through a family, allowing a younger changeling to take advantage of contacts established by the persona's previous users.

The changelings of Lorwyn are charismatic shapeshifters able to crudely mimic the forms of creatures and plants. Unlike most shapeshifters, however, their innate powers don't allow them to truly disguise themselves; rather, their transformations are purely surface level.
No matter their form, Lorwyn changelings keep their key traits: blue-green skin, tufts of tentacle-like fur, and bulbous yellow eyes with slitted pupils. The true changeling identity of a bug-eyed tree, teal elk, or furry boulder is always easy to spot. These counterfeits are so plain that many Lorwyn denizens find the effect inexplicably charming.
Changelings from Lorwyn live in a vast, mystical cave called Velis Vel Grotto. Once per year, many changelings make a pilgrimage to the grotto to contemplate their past deeds.
