[Intro — William, quiet, echoing the Architect's Number's intimacy] Every story needs a piece that holds the rest up. Take it out, and none of it was ever standing at all. [Verse 1 — echoing the Den's warmth] I opened every door I've got and told you who was walking through. Some of you I sang for softly. Some of you, I sang for who I once was too. [Verse 2 — echoing The Reached] Some of you were lost when we met. Some of you got found along the way. Every voice that joined this chorus had a name before it had a stay. [Verse 3 — echoing the Primordials] Five old powers built the framework. Five old shapes hold up the sky. I sang their names so you'd remember none of this was built on lies. [Verse 4 — echoing Boss Fights] Every hurdle, every hunter, every rule we've ever kept — none of it was ever easy. None of it was ever, once, a threat we simply slept through. [Pre-Chorus — building] Twenty-five songs, and one thing's certain. Every single one was true. Not because the world required it — because somebody had to. [Chorus — full, warm, everything converging] This is the Keystone. This is the piece that holds up everything I've sung. Pull it loose, and the whole thing scatters. Leave it standing — the story's begun, not ended. Just... held. [Verse 5 — quiet, personal, echoing The Architect's Number one more time] I don't know how many more there'll be. I don't know if the number's done. But I know the Architect keeps building, and I'll keep singing every one. [Final Chorus — the biggest the whole collection ever gets] This is the Keystone. This is the piece that holds up everything I've sung. Pull it loose, and the whole thing scatters. Leave it standing — the story's just begun. [Outro — William, warm, quiet, final] Come back to the Den sometime. The light's still on. There's always room for one more song.
