My two secondary (yet highly important) characters from my world/story of "Chronicles of an Errant Knight in the Most Esteemed Empire of Flowers".
Foc becomes her father's heir following the death of her younger brother; over the course of her life, she engages in a long-term relationship with Moc that ends with a "clean cut" (specifically, to a neck).
The dynamic between the two shifts from rivals to friends, then lovers, and finally enemies (with a touch of in-law kinship thrown in).
This is because, despite the love they feel for one another, a relentless pursuit of power and control remains the central axis of their relationship.
Foc is born into power, though her authority is constantly challenged due to her gender, while Moc is born with a certain measure of power but hungers for far more.
In the future, I'll make a better, colored version... maybe.
