Flame • hereditary boons that are specific to bloodlines and individuals, supplementing their natural magic with various unique powers. Most mortals of this universe have Flame too weak to use.

Heat • how "hot" a Flame burns; dictates how powerful it is and how often its powers can be called upon. From strongest to weakest, the heats are: Dominion > Harbinger > Throne > Glory > Pillar > Wings > Servant.

Passion • the unique powers of a Flame - what its conceptual wavelength resonates with, broadly describing the powers it bestows. Passions can be incredibly specific, or very broad (ex. the Blue Flame of Victory). Every passion has a unique color associated with it.

Stoking • the act of making a Flame stronger, potentially enough to increase its heat into another. Not all Flames can be stoked. 'Stoking' generally involves doing things that align with the Flame's Passion (ex. a Flame of art is stoking by creating, appreciating, or collecting art). 

Shearing • the act of passing a Flame on, usually by having children (though there are other means of separating someone from their Flame). The process 'shears' and weakens the original Flame, usually almost completely.

Soot-seeing • the practice of reading an individual's internal Flame to understand its color, and therefore its Passion. Soot-seers can also vaguely tell if a Flame is capable of being stoked. It is a difficult and imprecise art.

Mneme
A Harbinger Flame born in Verebriva, having fled across the mountains to avoid persecution. He was caught on one of Tyche's trade routes, but allowed to live so long as he paid off his taxes through working at the Nest Egg Inns.

Peaches
The current Emperor of the Holy Empire, instated after the Blue Flame was found in his hands. The previous Emperor, Nereen, had been assassinated without an heir, leading to a national scandal. Peaches, being dual-flamed akin to a member of the Ardor, has soothed his people easily.

The Ardor
One of the major belief systems of the world, which believes that ten Dominion-Flamed individuals crafted the world from their Flame and bestow their blessings on certain individuals.

Fervor
One of the major belief systems of the world, which says that four creator deities unite to defeat the world-eater at the end of days. Pleasing one of the four creators can ensure a beneficial reincarnation in the next era.

Lacraya
A southeasterly medium-sized continent comprised of tundra, mountains, and barren scrublands with some minor forests. On its surface are the nations: Holy Empire, Verebriva, and Sendrea Kingdoms.

Verebriva
The northernmost nation on Lacraya, made up of cold, harsh snowlands and dense pine forests. Verebriva has historically been abused by powerful Flames and is incredibly adverse to their presence. They are self-sufficient and value independence. Verebriva is ruled by the Crown, a title passed to the winner of a decennial tournament of duels.

The Holy Empire
The largest nation on Lacraya, encompassing the land from Verebriva's southern mountains to the continent's southern coastline. Most of its cities and towns hug the Savalla River. The use of Flame to supplement its peoples' lives has enabled small villages to thrive. It is ruled by its Emperor, who passes down the nation's sacred Blue Flame to a chosen heir after their reign.

Sendrea Kingdoms
A western coastal nation comprised of many small duchies that unified over taxation and trade. One of the wealthier countries in the world, it boasts a strong navy and numerous trading fleets. With dazzling cities on stunning beaches, money and ambition flow freely. Its leaders are the Crown Council, the heads of the twelve founding noble families.
