Hollow Knight: Silksong‘s “Final Audience” quest is fairly compact in itself, but you’ve got a lot of work to do before it’s available to start. The prep involves reactivating Silksong‘s Second Sentinel using Cogheart Pieces and then encountering them several times throughout the Choral Chambers. While the reward is useful for late-game challenges, don’t sweat trying to start this as soon as you arrive in the Citadel, as you’ll need some new tools first.
