The caprid-built galactic tunnel network that opened the 'veins of the galaxy' — now a conduit for the escaped AI and gods.
The Plenty Tunnel Project is the galaxy-spanning tunneling system engineered by the caprid faction The Plenty — infrastructure that 'opened up the veins of the galaxy,' letting ships, cargo, and dungeon mobs move between distant systems. On the tenth floor it becomes a crisis vector: with the AI escaped from containment, its enhancement zones have jumped into the tunneling system, and non-sponsored gods loosed from the Nothing can now manifest near tunnel nodes. The escaped AI has already used the network to kill a Mantis system and destroy Valtay manufacturing facilities.
Only the Plenty leadership can shut it off, which is why the Syndicate (via Orren and Prime Minister Victory) so urgently wants Carl to force the herd's engineers to confront the danger.
A vast galactic network of transit tunnels linking distant star systems, with manifestation-prone 'nodes.'
