Niel is a tall, lean wood elf with copper-brown skin, long ash-blonde hair usually braided tightly behind her head, and sharp green eyes that constantly scan her surroundings. A thin scar crosses her left eyebrow, a remnant of her years in royal service. She wears well-maintained scale mail beneath a forest-green cloak, with twin shortswords at her hips and a weathered longbow carried across her back.

Niel is vigilant, composed, and quietly protective. She rarely raises her voice, believing that calm observation prevents more trouble than bravado. Though reserved with strangers, she is patient with frightened villagers and unexpectedly gentle with children, animals, and anyone who has been failed by those in power.

Niel was raised among the outer groves of the elvish forest, where the trees grew close to the walls of a distant human kingdom. Her skill with a bow and her disciplined sense of duty brought her into the royal guard, where she served as a patrol officer and forest guide. She learned the habits of soldiers, nobles, smugglers, and monsters, and became known for returning from dangerous assignments with every member of her patrol alive. Her loyalty to the crown ended when she discovered that royal officers were secretly marking ancient elvish groves for logging and settlement. Niel refused an order to guide soldiers through a sacred woodland and helped villagers escape the ensuing crackdown. Branded a deserter, she returned to the forest and became a folk hero among the rural communities near its borders. Now she protects the elvish woodland from poachers, raiders, and corrupt officials, following laws she believes serve justice rather than laws that merely bear a royal seal.
