Doom is the Old English word for fate, for law, for judgment — and in Tianmu it serves as our word for dharma: the law that sustains the universe, makes it run, and ultimately consumes it.

Doom is also the name of Sagittarius A* — the supermassive black hole at the centre of our galaxy, the axis around which all life in the Milky Way revolves. It is one of the Twelve Ghosts of the Twelveness, and in Tianmu's comparative interpretation it is identified with the Demiurge: the force that holds creation together and is also the force that will devour it.

On the personal level, doom is your nature — what you are on a deeper level, the thing you must find and abide by. Your doom is not imposed from outside; it arises from within, from the Yarn of your own karma and the Hamingja of your ancestral line. To find your doom and live it honestly is the central imperative of a well-lived life. To live in misalignment with your doom is to suffer — not as punishment, but simply because a thing that denies its own nature cannot be at peace.

Doom is closely related to Wyrd, but they are not the same. Doom is the law itself — impersonal, vast, the wheel that turns. Wyrd is the personal encounter with that law as it unfolds through one's own choices, with all the irony and narrative drama that entails.

The Doomsayers — Tianmu's prophets — bear their name because their actions turned the wheel of doom for all of humanity. They are the rare beings whose personal wyrd became inseparable from the doom of the species.
