Raziela saw the value in having a sentient magical item with the ability to monitor and control systems throughout a massive fortress and created such a system for the Death Spiral Machine. This became the Intelligent Relic Information System Ver. 4.2.
While the system apparently has many safeguards to prevent it from betraying Raziela or the Spiral Eclipse, it still retains all of the memories of Iris Four, and thus has a fairly substantial grudge against Raziela and The Party.
Shortly after the defeat of Captain Rangrim Rustbeard, IRIS 4.2 used the Death Spiral Machine to trap The Party within her system, subjecting them to a bizarre parody of their own adventures within the Prismatic Vortex.
