The Undercrack

• Where: the Undermere, a new tunnel undercrack that climbs from the Undermere to the underside of the Heart Pane. Spawn Spawn_undercrack_foot; exit Exit_pane_underside up to the Pane's south rim.
• When: act4.stage = 1 and the player is refused at the inner-ring picket: Warden pickets turn back players whose morality is below the gate threshold, that is −20 or lower (Fallen; Codex section 7). (Idea) undermere.stage ≥ 1 also opens the tunnel to anyone who wants it as a shortcut.
• Who: the player; Rook, if rook.trust ≥ 2 (Tamsin won't take the outlaws' road and meets the player at the rim); an Undermere smuggler.
• What happens: (Idea) A crack under the Shardfield climbs to the Pane's underside, where the Undermere's upside-down reflection of the world (Story Bible section 6) meets the Pane's real one. From below the player sees what neither camp can: the Pane is already cracked from underneath, and both rites are pulling on the same crack. Outlaws of both sides are camped at the top, waiting to loot whatever is left. This is the evil path's way to the act. It is not a punishment: all three paths stay open from here.
• Player does: move; talk; fight (outlaw casters at the climb, optional to avoid by talking).
• Content to make: location undercrack; Yarn Act4_Undercrack_Smuggler, Act4_Undercrack_Underside. Encounter undercrack_outlaws (an Evane outlaw, forsworn_mender, then a Facet outlaw, hollow_cut; see the bestiary). Flag act4.saw_underside = 1. No stage change here; arriving at the rim (4.5) sets act4.stage = 2.
• Art and audio: tunnel kit (reuse the Undermere kit); the Pane's underside as a ceiling of glass with the sky behind it and the camps' lights as blurred shapes. Music: Undermere theme.
• Screens used: dialogue box; battle HUD.
