Yanìs Chronicles:
Savage Crowns

Madra is one of the offspring of Thialon and Kudan, and the sibling of Dekar.

It was born out of corrupt morals and the poisonous words of the world, and is known as the Spark of all Evil, the Rust of Society, and the Infamous Deceiver. It is considered the spiritual guide of all corrupt officials and the puppeteer behind every failed deal.
Nettle, wasps, and rust are sacred to Madra and are required in sacrifices and ceremonies. Its priests wear light grey robes with primarily ocher and white decorations and are trained in combat with spiked maces, which cause more pain than they should. If not aimed directly at the head, these attacks cause fractures and bleeding that slowly kill the victim.

Madra is one of the most feared deities by mortals because its deceptions are subtle and difficult to detect unless it is already too late. It is a chaos-bringing deity who enjoys witnessing the decay of others, but it is not a deity of pure and primordial chaos. According to Madra, chaos is a subordinate consequence of order, which cannot exist without order. For this reason, Madra suggests to its followers to act where order is already established, stealthily moving to make it collapse, like rust that slowly corrupts iron. It delights in bringing discord, spreading falsehoods, and causing bad moods. All that is good and well-organized goes towards decadence, and the followers of Madra see this as their main goal. Their plots and deceptions woven between the hallways of mansions have the purpose of slowly crumbling everything that works well.
Madra has learned from Kudan the cunning art of poisoning, though it applies it to words instead of blades. It often goes along with the dupe Dekar, as pride and wealth are often the best means for corruption, but it is in open contrast with Thialon, who fiercely believes in order and absolutism.

Madra shows itself as an anthropomorphic chimera made up of parts of all kinds of animals. It has legs and eagle-hooked feet, the head of an albino cobra, huge membranous bat-like wings on its back, and its chest and arms are covered with fish scales. It also has a long retractable toad's tongue.
