The gods were giving us a warning...
The shift in constellations was a warning from the gods themselves. The other incidents of missing people and the disease 'Fastrot' was all the doings of Milara and his latest attempt to become a god.
He was using a device called The Conduit to try and syphon off divine magics from people who were inclined to have such magic. This was...I think..was causing the 'Fastrot' as it was making people dissolve into gory puddles. Didn't have a chance to see this and not sure I wanted to.
Anyway...using a device called the Failsafe...we tracked the Conduit to the Mountains of Madness where we disrupted Milara doing something...couldn't tell what. He fled and we killed his undead soldiers and his Triumph and vaunted Pet. Big time blow to him. He has vanished to lick his wounds and plot again. We haven't heard the last of him.
The Conduit is being returned to its rightful place with some gnomes we encountered in the woods near Leringard. They were a little dismayed at the tinkering Milara did to it...but they're gnomes...they can probably undo what he did to it. Crafty little buggers they are.
All is well again...until the next crisis strikes. Wait till I tell Ferrit I helped defeat Milara somewhat...
