Things cooled back down after the characters returned from Mars, the wizards involved in the raids are on trial and the story made global news. As the characters are relaxing at their favorite hangouts they get notice that God Squad has another request on the line.
Years ago in Dimension 13491 a group of renegade fighters set up a secret base on an ice planet to launch attacks against the government. Some time later traders set up on the planet to harvest the abundant ice and trade it to arid worlds where water was scarce. Operations ran into trouble with the local ice monsters which don’t show up on sensors which was trouble enough, but in a recent report the dead soldiers from the old battlefield have risen up and attacked the operation.
The traders wisely pulled out, but reported the even and the concern is some power may be taking hold on the frozen world which could potentially spread. Concerned parties would like the God Squad to investigate and determine if it is an isolated incident or cause for alarm.
A rift to the area should be able to put the team within a week or less of the planet in question (A gate could put them on the base itself, but they would be limited to small vehicles or traveling on foot).
