These are art pieces and concept art that I used for a D&D campaign that I ran!
The story is that a king, king Namida, had a son who died young, inflicting Namida with unconsolable grief. His lamenting attracted the attention of a malevolent deity who offered to help, but his help came with the curse that the kingdom Namida ruled over would be afflicted with constant, downpouring rain, that washed away the residents memories, freeing them from sadness but losing their minds in the process. The rain eventually began to crystalize into shards of onyx that formed hands, enveloping the victim over time as they finally become mindless husks.
