Nichol is a compact gnome with a tan, copper-like complexion and striking metallic-silver hair styled into sharp spikes. He wears well-worn studded leather that has been meticulously polished to shine under stage lights. His primary instrument is a strange, oversized lute with visible internal brass gears that hum with a rhythmic vibration. Around his waist, several iron drumsticks are tucked into his belt, alongside a collection of small nickel charms that chime as he moves.

Nichol is obsessively rhythmic. He speaks with a natural cadence and often taps out beats on his thighs or armor during conversations. He views the world as a series of interlocking tempos. He is gregarious and friendly, but he becomes intensely serious when the beat is off, believing that a sour note is a sign of cosmic imbalance.

Nichol was once the lead metronome for the famous gnomish warren band known as Nichol L Bak. Alongside his brothers, Leonidas and Bakker, he pioneered a style of music known as heavy metal percussive resonance. They were legends in the underground circuits until a creative rift formed. Leonidas wanted more melody, while Nichol believed the secret to the universe lay in pure, crushing rhythm. The band went on a permanent hiatus, and Nichol took his mechanical lute and set out into the surface world to find the legendary Grand Echo. He travels now to share the sound of the deep caverns, using his music to blast through obstacles and bolster the hearts of his allies with steady, driving beats. He carries the 'L' and the 'Bak' in his heart, hoping that one day he will find a performance great enough to reunite his kin.
