Kairos Fateweaver

Even Tzeentch dares not enter the Well of Eternity, the vast receptacle of knowledge at the heart of the Impossible Fortress. The Great Sorcerer, mighty though he is, cannot be sure of survival within the inky currents of infinity. Still the Well of Eternity holds great sway over Tzeentch’s mind, for it is the one puzzle he cannot solve, and the one mystery he cannot know — a challenge almost painful in its intensity. It was in the cause of understanding that Tzeentch hurled Kairos, a Lord of Change known as Fateweaver to mortals, into the foreboding depths of the Well. While the Great Sorcerer was not prepared to risk his own being in such a venture, he had no such misgivings at risking one of his servants in such a fashion.

Since he clawed his way back from the Well after years uncounted within its depths, Kairos can see things that are hidden even to Tzeentch. H is right head sees possible futures as clear as day. N o scheme is hidden from its sight and the infinite possibilities of tomorrow crystallise into irrefutable fact. Kairos’ left head sees the past without the petty colourations of perspective and bias. Past and future pulse through a body shrivelled and twisted by its passage through the Well. Valuable as this vision is, it comes with a heavy cost. Both of Kairos’ heads are blind to the present; he cannot see time as it passes — only events that are to come or whose time has already lapsed.

Kairos now sits at Tzeentch’s right hand, stirring the stygian depths of the Well as he whispers aloud the secrets that only he can see. Nine times nine Lords of Change transcribe these insights with quills drawn from their own plumage and inked with Tzeentch’s blood. Each scribe jealously guards the secrets he hears — every such facet o f eternity is a powerful tool in the unending intrigue and collusion of Tzeentch’s court. For his part Tzeentch cares not about the scheming of his minions, for he knows all that they know. Each secret transcribed by a L ord of Change is made a part of Tzeentch forever and his understanding of eternity comes ever closer.

Kairos’ blindness to the present makes him vulnerable to physical attack — the future does not reveal itself swifdy enough to predict batde’s to and fro. Nevertheless, Kairos’ unique vision allows him to stay one step ahead of adversaries, pitting various assailants against one another in timestream-straddling duels. In the arena of magic, Kairos is unstoppable. H e knows every spell in existence, every sigil, sign and quirk of mystical power; though even he cannot marshal them all without a modicum of preparation. Such ability makes him Tzeentch’s favoured agent. On the occasions Fateweaver leaves the Impossible Fortress it is always in the service of a dire task, be it the recovery of a magical artefact, the predestined crushing of an army, or some other ineffable purpose.
