Prisma is among the highest ranking - and most dangerous - Tower Mages. She has been studying magic most of her life, as it runs in her family. Her talent and determination have given her a high standing within the Tower.

Like all Tower Mages who finish their core training and begin to specialize, Prisma wears very distinctive robes. She wears a light brown Robe of Scintillating Colors, with a rainbow-colored triangle running from her right shoulder to her left hip. Her dark red straight hair has streaks of blue, green and yellow dye running through it, giving her hair a rainbow look similar to her robes, and her eyes are a dark shade of blue. She has a corollax familar, but rarely lets him out of the Tower. Her charm, beauty and charisma are enough to seduce a titan (which she did).

Prisma worships Merdrekhal, so it just seems natural to her that the most beautiful things in the world should be hers, even if she has to take them from their current owners: hence her reprehensible actions on Utopia Island, where she and three of her students sought to force their way into King Yanel's Ivory Tower to gain access to his spellbooks.

Once that failed, Prisma sank to a new low. A month later, she seduced Yanel, married him, then turned him to stone and stole his spellbooks. Thinking that she had gone too far, and wishing to avoid a confrontation with Yanel (who is a powerful spellcaster), the Tower declared her and her three students renegade mages. The three students were later killed and Yanel and the island restored, but Prisma disappeared. The Tower is currently searching for her to bring her to justice. Two Tower Mages, Geller and Dante, have been assigned to the case. A third one, a Tower Mage known as the Enforcer or the Exterminator, has taken a personal interest in this case and is also seeking Prisma, presumably for the same reason.

After fleeing Utopia Island, Prisma traveled to the Temple of Unseen Poison in Douran, wherein she attemped to gain access to the Chronicles of the True Events of the Second Era, a much sought-after book containing highly valuable information. This book had been stolen from the Temple of the Illuminated Heaven years ago. Some parts of the book were accurate, but much of it had been falsified by the chaos elves. Upon learning this, Prisma made some deals with Amaxanthen Naraxanaya, the temple's high priestess, to find out what information had been changed, and what fate had befallen the actual book. Prisma left the temple just hours before it was finally destroyed by an earthquake. Whether she ever found the real book or discovered what changes had been made, is still unknown.

Prisma is 30 years old, 5'8", right-handed, and chaotic neutral with evil tendencies. She is confident and relentless in pursuing her goals, and thinks nothing of removing anyone who opposes her.

Prisma is still at large. She is considered armed (with powerful spells) and so extremely dangerous it hurts just to think about it.

The Tower Mage known as the Enforcer has recently revealed herself as Penumbra. Although no personal connection to Prisma was stated, some people may have noted a certain physical resemblance between the two.
