Lilitu Geisthexe's normal tasks are usually a bit more hair-raising than this was supposed to be. Grímsvötn volcano in Iceland was getting ready to erupt. This happened every so often, just like most active volcanoes. Most of the time it happened, it was over and everything was done, no harm done. But then there were things like Krakatoa. And that's where the group from Yomi figured in. Just in case it was a major eruption, they were supposed to do what they could to prevent it from making the Earth a little less liveable. Preferably without anyone noticing who wasn't supposed to notice.
But there is a ripple this time around that no one is expecting. Something potentially worse than even the concept of a volcano ripping Iceland off the map and putting the world through a year long winter.
These events take place roughly the same time as the events in the Deployment chapter of the Divine Blood novel already available here.
