R'hllor
R'hllor, alternatively known as the Lord of Light and the Red God, as well as the Heart of Fire and the God of Flame and Shadow, is a deity widely worshiped in the continent of Essos. The Lord of Light has been described as a "fire god" and its clergy "fire priests", as worship of the Lord of Light centers around fire and light. It is the majority religion in several of the Free Cities, and extends to Asshai in the distant east. Worship of the Lord of Light is almost unheard of in Westeros.
The religion of the Lord of Light is centered on belief in the existence of a single, all-powerful god. R'hllor is the god of fire, which provides light, heat, and life, and struggles against darkness, cold, and death, represented by an opposing deity, the Great Other.
Due to the dualistic worldview of this religion, its more fanatical followers believe the Lord of Light is the "one true god", and all other gods from other religions - The Old Gods of the Forest, the Faith of the Seven, the Drowned God, etc. - are demons and false idols that must be cast down and burned.
The Lord of Light's worship involves the idolization of fire and light. Shadows are important too, as they are "created by light". The religion is very focused on prophecy, and on ecstatic visions that are received through communion with the flames. Melisandre claims to receive visions about the future from the Lord of Light by staring into fires.
Unlike the religions of the Old Gods in the North or the Drowned God of the Iron Islands, the faith of the Lord of Light is stated to possess several holy texts, similar to the Faith of the Seven.
While the Faith of the Seven believes in Seven Heavens and Seven Hells, in the Lord of Light religion the current world that everyone lives in now is considered to be "hell", the only hell, but the Lord of Light will save his faithful adherents from this darkness.
The followers of the Lord of Light also believe in the coming of a chosen warrior to combat the coming darkness, The Prince That Was Promised, who is prophesied to be reborn "amidst smoke and salt" and wield the sword Lightbringer.
