The Jester (Patreon)

Jester is one of the NPCs on BBEG's side in our Sunday session D&D campaign. He staged a murderous play for our party during which hundreds of people died since we were not able to save them all (One of our party members died in the process and we went on a whole big side quest to bring her back to life). The play involved us stopping deadly sins roaming through the city. Every sin was an NPC wearing a cursed ring which we had to acquire. Stopping one sin would mean saving 100 people. We stopped only 3 of them and now we're about to face the rest in the next city we just entered.
He speaks in a whispered voice, moves without a sound and can appear out of nowhere. Never posed a threat to us personally but collecting all of the sin's rings will get us to him for most likely a big boss fight~

The design is loosely based on Daria Rashev's design who you can find here.
