K'lyhia is an assessor working at Mealvaan's Gate. She was assigned by Thubyrgeim to oversee the adventurer's first assignment with a cargo assessment training exercise near Zephyr Drift in Middle La Noscea. The adventurer will later be assigned to assist her in an official inspection of goblin traders suspected of carrying black market goods, which she predicts will turn violent.
At arcanist level 15, she will teach how to summon a Topaz Carbuncle, in preparation for an upcoming assignment: the inspection of the suspicious merchant vessel Morningstar. Though the crew was subdued, before they can check the cargo, it is discovered to be commandeered by an old nemesis, Doesmaga Poisonheart. K'lyhia faints from the shock of the encounter, and her grimoire is tossed overboard. It was later revealed that she had previously had been a prisoner of the pirate, and the grimoire was a gift from the guildmaster K'rhid Tia.
After recovering her grimoire from a black market merchant at Oschon's Torch, it was discovered to have been too heavily damaged by seawater to be of use, causing K'lyhia to sink into despair. Thubyrgeim asks to find the absentee guildmaster, seen recently in Upper La Noscea. After following his cryptic tasks, he presents a replacement grimoire for K'lyhia, and asks the adventurer perform a dance emote for her so she knows who it is from.
With her new grimoire and restored confidence, K'lyhia orchestrates a plan to capture Doesmaga off Bloodshore and bring him into Lominsan custody. Following her complex instructions at Costa del Sol to prepare her trap, the adventurer arranges for sneak aboard Doesmaga's vessel, with the adventurer posing as a wine merchant and her as a dancer. After besting him and his men atop the deck of his ship, Doesmaga tried to flee overboard on a lifeboat, only to be cornered by Yellowjackets she had arranged to move in based on her predictions of his moves. With the pirate outlaw now in custody, K'lyhia announces her intent to seek out the guildmaster and leaves on a sailboat.
K'lyhia is a female Seekers of the Sun Miqo'te with pink hair and fur, dressing in a navy blue half-robe, black tights, brown boots and ringbands. Her weapon is a black cover grimoire.
K'lyhia can be seen fighting alongside the adventurer in many arcanist class quests. She is an arcanist who fights with her Topaz Carbuncle.
