Born a half-elf in Erin's Great Forest within the Grasslands, Meneldor faced ostracization from both human and elven communities due to his mixed heritage. This rejection drove him to leave his birthplace and seek life as an adventurer. During his adventuring career, betrayal by a party member resulted in poisoning, the death of his companions, and his own near-fatal injury. After killing the traitor, Meneldor fled weakened into the Beast Woods where Marple found him. This trauma led him to abandon adventuring and settle as a local hunter in that forest.
Meneldor possesses silver hair and jade-colored eyes. His distinctly elvish features contribute to a noticeable beauty often perceived as feminine. This appearance draws frequent commentary, causing him self-consciousness when others highlight his feminine aura or tease him about it. Shaped by past betrayals and isolation, his personality manifests as initial wariness and quick judgment of others' intentions. Over time, interactions foster greater open-mindedness and friendliness, though he retains a blunt tendency to speak his mind.
His primary abilities center on Elementalism, utilizing specific incantations called Words of Creation. Documented spells include "Slip" to trip opponents, "Fire Breath" to scorch targets, "Hold" for immobilization, and "Stone Fist" for striking. He employs "Ochre Dust" to create obscuring whirlwinds and protective spells like "Protection From Arrows". Mobility and control spells in his repertoire encompass "Tailwind", "Waterwalk", and "Waterbreathing". Additional unnamed spells involve amplifying spellcasting via wind sylphs, denying flight to enemies, and a self-sacrificial healing spell that trades his vitality to restore others. He typically serves in combat as a long-range support specialist.
Meneldor's relationship with William begins after William departs the City of the Dead. Their initial encounter evolves into a profound friendship, marking Meneldor's first genuine bond and significantly influencing his personal development. He adopts William's guardian deity, Gracefeel, shifting from his previous beliefs. Meneldor acts as a cynical counterbalance to William's idealism, frequently addressing practical concerns like rewards and moderating William's chronic heroism. He offers candid advice and admonishment when necessary, establishing himself as William's closest advisor. Meneldor acknowledges the challenge of their mayfly-december friendship, recognizing his half-elf longevity against William's human lifespan, yet vows unwavering loyalty to William's descendants.
His story includes participation in the key expeditions "The Archer of Beast Woods", "The Lord of the Rust Mountains", and "The Torch Port Ensembles". His name originates from J.R.R. Tolkien's legendarium, where Meneldor is an eagle; the Elvish translation means "fast flying eagle".
