Dubi Gan looked at the corpse, who is now nothing but a faint blurry outline. He remembered a scroll he once read, a fragment "rescued" from fallen Syr Daria. In it, it spoke of a type of person who was overcome by greed - so much so that they couldn't abandon life and rejoin the Wheel of Reincarnation. These spirits were called Preta, and they were cursed to gorge on vile things - their appetites insatiable even though they hated the stuff. You realized that legends you heard as a kid matched this description - and that those legends specified that the Preta couldn't be harmed saved by magic or blessed weapons.
Frog Froth, you think that the bodies have been dead quite a long time, although you get a general sense that the deaths were not at the same time. Their equipment and clothes are decayed long past salvaging. However, two of them were carrying a substantial number of coins - 2000 coppers, 900 silvers and 30 gold pieces.
(Which is the equivalent of 631.25 rupees. It's not a fortune, but if you gave up and turned back home now, this expedition would count as a success).
I would like awareness checks to see if the party finds anything else.
