A humming and vibrating rhythm cycles through this room. Plastered walls engraved with shimmering copper wires terminate in a door to the south and another to the west. A series of lit-up panels and instruments in the east wall are being monitored by three wraiths while ten skeletons stand awaiting instructions. Every twenty turns a small group of tourists emerge from the south; they act as the free dead tourists from (6.19). The wraiths and skeletons will defend the machinery against attack. If the panels and instruments are destroyed, the free dead star manifold will destabilize in 2d10 weeks. If the Necro Engine in (5.9) isn’t functioning, the manifold will be “closed for maintenance” and no tourists can arrive or leave.
