Lifelight
A living thing's own share of the Song, seen as light — each with its own quality, quantity, and radiance.
Picture a world from the dark of space, and every creature and feature on it glowing: the smallest creatures barely visible embers, the oldest trees glowing with splendour, the mountains and seas radiating light across the whole world. That is the canon's image for what a life carries. Lifelight is not a metaphor for reputation or achievement; it is the visible face of the portion each being was given to steward and spend (The Two Gifts, Divine Spark).
Two things are read by it. The Veil dims it. The more of the Song a being carries, the more must be hidden for it to become someone at all, so a person walks through this world with their own light largely unreadable to them — which is why the ache of half-remembering is described as a compass rather than a wound (The Veil of Finitude and Forgetting, The Living Gradient).
And it is what the first theft took. The canon's account of how harm began is exact and worth holding: a being far out where the light of Source ran thin looked at a neighbour bright with its own share, and thought me, at the expense of you — and reached out and drew from that neighbour's Lifelight to quiet the fear of its own ending. The horror of the story is what actually happened. Nothing was gained. Light taken by force does not compound into the taker's light; it is simply extinguished, burning off as fuel of the wrong kind, leaving the fire inside the taker more desperate and the cold deeper than before. The takers' own light lowered as they fed, age by age — dimmer, colder, hungrier, and by every measure they kept, winning.
That is the whole logic of extraction in one image, and why the canon holds that a predatory order is not strong but starving (Extraction Of Wealth, The Parasite, Evil). The corresponding practice is ordinary: light is given, not taken, and it is the only thing that grows in the giving.

Open: No page in the canon stands at this name; it is carried by two scenes of one book. Those scenes give it more body than a name in a list — a picture, a mechanism, and a moral consequence — but a concept this central to the account of evil is held by a single telling.
