Flame User class series

The Flame User class series is the default class series available to the Mars Adept Jenna, who is under the influence of this class series if she either has only Mars Djinn or no Djinn set onto her. The Flame User Class series is unique to Jenna in Golden Sun: The Lost Age, as she is a mage while Garet is a fighter. Garet has a different Mars-based class series unique to him, the Guard class series.

Jenna as a Flame User was available in the Sol Sanctum dungeon at the beginning of Golden Sun; however, she only had access to the Flare Psynergy series and could not change her class because there were no Djinn available at the time. The rest of her classes and Psynergy were revealed in The Lost Age.

Statistical Influence
Carlin (the Japanese name for the Hex class) is a Scottish term for a woman, particularly an aged one. The intent might have been "wise woman", considering the presence in the Japanese of a "Sage" step (the equivalent of the Justice class).
