Dustmaker

Dustmaker is called the prince of decay and ruin. They have been worshipped as one of Mesnea's demon princes for all of recent memory.

Their symbol is usually a glass pendant that either acts as a small terrarium or is filled with sand.

If manifested, they're said to wear a mask and clothes carved from stone with moss and ivy growing over them, and they're said to rapidly disintegrate the land around them.
