Song of the Serpent
The Song of the Serpent is mythology, religion, philosophy, bardic legend, and a way of life for those invested in the culture of the dragon. It is a mystical retelling of an ancient story involving the unification and dissolution of the gods Tiamat and Bahamut. The Song has been known to civilization for many thousands of years. It is thought to have been composed by a sect of mystic dragonborn bards of Dendrith.
Storytellers familiar with the tale are few in number. Time has relegated the Song to obscure mysticism. Obscure during even the Previous Eon, the Song has survived in a few small pockets of civilization in Annoril, most notably among the human clans of the highlands south of the Broken Kingdom.
According to the Song, the Great Maker created the god Io, who was granted dominion over all dragonkind. In the war between the primordials and the gods that occurred shortly after the multiverse was born, a primordial known as the King of Terror attacked and slew Io and the god's dragon defenders.
The two halves of Io arose into separate deities: Bahamut, representing justice and righteousness; and Tiamat, representing greed, lust and envy. The two battled incessantly throughout the millennia, both eager to destroy the other though each was part of the same whole. The Song of the Serpent gives a lengthy poetic, philosophical discourse on the necessity of each part to give meaning to the other, and the irony that good would be wholly impotent without the contrast of evil (and vice versa).
The Song of the Serpent continues with meditations on the endless cycle of birth and rebirth: the waxing and waning of good, then evil, then good again. This troubled and difficult part of the narrative alludes to the existence of a powerful mystic ritual that, if cast properly, might reunite the two halves of Io, subsuming the part represented by Bahamut and creating an evil superdeity and an interminable age of darkness.
The Song's conclusion is ambiguous at best. It alternates between the inevitability of the death of Bahamut and hope for a hero to rise and stave off Tiamat's cruel reign. The Song of the Serpent remains impartial in the discussion of the multiverse's fate, placing the decision squarely upon the listener. Scholars have interpreted this as a parable to instruct the listener that the world is what the individual makes of it.
