The Nexus Chamber — Engineering Core

GM-only enemy positioning (place at scene-open, as the Keening manifests): the Keening centered on the plinth at roughly [7, 5] (purple; three times a person's height). It CANNOT be killed directly — incorporeal, reforms; resistant to Energy/Kinetic, immune to grapple/shove/prone. The RELIQUARY (the object on the plinth) is the target: AC 15, HP 40 (2 PCs 24 / 3 PCs 32 / 4 PCs 40 / 5 PCs 48 / 6 PCs 56); resistant to Energy + Kinetic (blasters/melee deal half), full damage from Force powers, lightsabers, Ion, and explosives. THE CLOCK: on any round the party deals NO damage to the reliquary, the Keening Wails (every living creature: WIS save vs the Keening's Force DC or Frightened 1 round) and raises Hollowed per the Manifestation scaling table (1-3 husks, TR 1, HP 16) — place them at roughly [5, 9], [10, 9], [7, 11]. The party must screen the damage-dealer, control the rising Hollowed, and break the idol before the chamber fills. Anti-TPK dramatic save (once): if Bex is alive, he jams his welder into the plinth base (Keening loses its next Wail; reliquary drops to half if above it) at the cost of his life; if Bex is dead, the reliquary overreaches to seize the strongest Force-user and is exposed (same effect). Non-Force paths to damage the idol: an Ion charge from the loader droid (1.2), the reactor-feedback pulse (Mechanics DC 16 at the west control), grabbed explosives, or concentrated fire over more rounds.
