there might possibly be an expedition from Mechanus finally seeking thelost Modron Division. Then the PCs have the quandry of meeting live modrons in a fortress full of 'dead' ones. They then might have to decide if waking up the 'dead' modrons is worth the possible trouble they might unleash.
A portion of the Modrons could have become corrupted by Chaos on its way through the rift, when they arrives the corruption germinated and finally a Modron Civil War erupted. THe chaosdrons won and now control the fortress but only the deactivated Modrons know the secret the PCs seek. In a similar way perhaps there are two portions of gods essence within the fortress, one each exerting control over factions of Modrons (while exploring their new environs they found them)---->Modron Civil War---->winning faction now controls the fortress (the winners are obviously not the Modrons the PCs want to talk to)---->A rival group seeks both essences -one for themselves and the one the PCs seek to sacrifice to a rival deity or some such---> The PCs now have contend with both the Modron Faction (who are not going to give up their essence) A rival group (seeking the Live Modron essence and the Dead Modron essence) and have to reactivate the Dead Modrons to find the essence they seek.
