Mielu is a slim, long-limbed wood elf with moss-green eyes, russet-brown hair braided with small juniper twigs, and warm bronze skin weathered by years beneath open sky. His hands are broad-palmed and rough, with darkened nails, tiny cuts, and stubborn stains from soil, sap, and crushed leaves. He smells strongly of pine resin, damp earth, and smoke from green wood, an odor he considers clean and comforting. He wears patched leather armor beneath a faded green cloak, carries a round wooden shield marked with concentric growth rings, and uses a polished quarterstaff that still bears living buds near its grip.

Mielu is gentle, earnest, and intensely observant. He is fascinated by ordinary human behavior, especially doors, shoes, markets, and written contracts, but he often misunderstands why people use them. He has the calm patience of someone who can wait beside a burrow for hours, yet becomes startlingly decisive when an animal, plant, or habitat is threatened.

Mielu was raised in a quiet elven settlement built among enormous spruce trees, where the oldest inhabitants served as keepers of a shrine dedicated to the patient, breathing world. He was sent to the shrine as a child because he asked too many questions about why people were allowed to cut trees, dam streams, and cage animals. The priests taught him sacred rites, calligraphy, and the names of old spirits. Mielu understood the rituals perfectly, but he never grasped why the temple treated the rules of civilization as more important than the rules of the forest. As he grew older, Mielu wandered farther into the surrounding jungle and learned its laws from observation. A vine strangles what climbs too high. A jaguar kills because it must eat. A fallen tree becomes shelter, food, and eventually soil. To Mielu, this is not cruelty or chaos. It is order. When loggers burned a nesting ground to clear a road, he confronted them with a solemn list of every creature displaced by their work. When they laughed, he answered by calling roots through their wagons and driving them from the grove. His temple praised his devotion but worried about his naivety, so they sent him into the wider world as an acolyte and protector. Mielu now seeks anyone threatening the natural world, confident that every problem can be solved if people simply obey the jungle's rules.
