Chapter 3. The Source
The Blight does not flow into the funnel — it flows OUT of it. Beyond the stone there is only the bottom.
Chapters
The last chapter lies entirely in the sixth land: clear the gate, release those the funnel drags down, break open the pit, raise the names from under the barrow, speak with the Obelisk, descend the rings of steps and meet the Source.
It has no upper bound and cannot have one: after the Source the game does not end but turns into the endgame and the tiers. And after the fight comes a choice of three, and it stays in the save as a seal.
The chapter has 7 steps; it opens at level 55.
