Kesler Dizznee is the owner of an apothecary, Slurps and Burps, and an alchemist. He is renowned for his unorthodox elixirs and crazy brews, as well as his multicolored shop, designed in just a way to make nobles and high class people squirm when they enter. He is well known for his powerful potions and is considered to be one of the best alchemists around. Despite this, he is also looked down upon because he is Talentless, and is considered a bad match, since his wife, Juline, was gifted the Special Ability as a Froster. He is also the father of triplets, which is usually considered disgraceful in the Lost Cities. He has a joking personality, plus is a very caring father and husband.
- JULINE (Wife) She has a Special Ability as a Froster. In Lodestar she is revealed to be Squall. When she reveals this to him he is taken aback and asks her many questions. She admits that while she did sneak away to see the Black Swan, Juline still told him where she was going and that the Black Swan was just a small detour. Kesler also often feels as if he ruined her life by marrying her, even if he did not. He is shown to love his wife very much.
- DEX (Oldest son)- looks exactly like his father, has a Special Ability as a Technopath. Kesler is shown to have a deep loving relationship with his son and is an amazing father to him. He makes sure that Dex knows how to use his abilities and talents and most likely gave him his prankster personality, as he is unable to hold back a laugh when Dex gives Stina a balding elixir. Being extraordinarily proud when Dex became a technopath, Kesler seemed like he wanted very much to brag. In addition, in Neverseen, once he sees his son again, he wraps him in a bear hug, pulling away with tears in his eyes.

In addition, he also tends to ship Sophie with Dex up until Nightfall.
