T = 0

T = 0 is a lore-entry record in Unveiling, introduced with Shadowkeep. Its creation parable describes the struggle between the Gardener and Winnower giving rise to universes and allowing the old garden's patterns to escape into the cosmos.

The original unlock route for Unveiling was to finish Beyond in the Shadowkeep campaign and visit Eris Morn on the Moon for weekly entries. This is a lore chapter, rather than a timed activity despite its mathematical title.
