Your physical form is entirely composed of non-living, organic materials animated by primal forest magic. Because you lack biological anatomy, flesh, and blood, your fundamental nature is that of an artificial creation rather than a humanoid creature.

Your height and build are determined by the physical dimensions the lost child gave you when constructing your body. You might be a tiny, compact doll or a larger, child-sized figure assembled from thicker branches.

Your lightweight, flexible frame allows you to navigate almost any terrain with surprising versatility. You can march gracefully along roads, burrow beneath loose forest loam, scale steep trees, or paddle through riverways with equal ease. Your base walking speed is 30 feet, your burrowing speed is 20 feet, your climbing speed is 30 feet, and your swimming speed is 20 feet.

Your anatomy is a patchwork of the forest floor. Lacking biological organs, you are resilient to bodily needs, though your dry, organic frame catches ablaze with terrifying ease. You don’t need to eat, drink, or breathe. You are vulnerable to fire damage. While you aren’t wearing armor, your base Armor Class is 13 + your Dexterity modifier. You can move through the space of any creature that is of a size larger than yours.

You have no concept of biological sleep. Instead of slipping into dreams, you enter a trance-like state of hyper-vigilance, keeping watch over your companions in the dead of night just as you once watched over a frightened, sleeping child. You don’t need to sleep, and magic can’t put you to sleep. Instead, you can enter an inactive, motionless state for 4 hours each day. You remain fully aware of your surroundings during this time and notice approaching enemies and other events as normal. You can still take short or long rests to recover hit points and resources while in this state.

Because your soul was kindled by the untainted, innocent imagination of a child, your mind possesses a crystalline purity. The terrifying psychic horrors that break flesh-and-blood creatures slide harmlessly off your consciousness.

Sickness, rot, and plagues require living flesh to fester. Your dried wood, twined roots, and mossy padding offer no foothold for biological corruption.

You carry the basic tongue of civilization overheard from your creator, paired seamlessly with the ancient, rustling whispers of the woods that birthed you.

The spark of raw imagination that birthed you granted you an incredibly sharp, fast-processing mind. Combined with your lightweight, flexible frame and an innate connection to the natural world, your intelligence score increases by 3, your Dexterity score increases by 2, and your Wisdom score increases by 1.
