Zook is a tiny, energetic forest gnome with wild, moss-colored hair tied back by a pair of brass goggles. She wears well-worn studded leather dyed in shades of deep emerald and charcoal to match the woodland shadows. Her fingers are long and stained with ink and grease, and she carries dozens of tiny pouches attached to her belt. Her eyes are a bright, piercing amber that seem to dance with curiosity.

Zook is a whirlwind of nervous energy who speaks at a mile a minute. She views every locked door as a personal insult and every secret as a challenge to be conquered. She is fiercely loyal to those she trusts, though her habit of over-explaining magical theory can test the patience of even the kindest souls.

Zook was born in the Whispering Woods, where she spent her youth talking to badgers and weaving light to distract her siblings. Her talent for illusion was unmatched, but she grew restless with the quiet life of a gem-cutter. Seeking excitement, she moved to the city of Silverymoon, where her small stature and natural magical aptitude made her an ideal candidate for the Hidden Network, a guild of spies. She specialized in infiltrating high-security archives to recover stolen memories and forbidden scrolls. Zook quickly earned the nickname Spark for the way she used magical surges to disable mechanical traps. Her career hit a snag when she stole a ledger belonging to a powerful merchant prince, forcing her to go underground. Now, she operates as a freelance operative, using her arcane tricks to stay one step ahead of the law.
