Rule 703.4e

Official source text from the 24 September 2021 Rules release

Immediately after a player’s precombat main phase begins, that player puts a lore counter on each Saga enchantment they control. In an Archenemy game, this happens after the archenemy’s scheme action. See rule 715, “Saga Cards.”
