Justice Light's killing ground, into which the Posse plans to funnel the Dreamer army once thinned.
Told that possibly the entire Dreamer army has teleported in, Justice Light tells Rosetta it is too many: "Chop 'em up a little first for me, Rosie. Get 'em down to under 3,000, then we can let them in."
He promises to welcome any and all guests into his lair, adding that he would prefer them to be The Reavers but will take what he can get. The exchange establishes the lair as a deliberate trap with a strict capacity, and part of how the Princess Posse plans to destroy The Dream's committed army.
A prepared trap with a 3,000-enemy intake limit.
