The kingdom of the North is known for its many disasters and demons. From the cursed trees to demons born of pain, there isn't a town you can find that has had peace for long.
Yet still the people persist. Silver is one of the few who actively work to stave off the encroaching disasters by being a Plague Keeper. He dawns his thick uniform and mask and goes to the locations of plague demons, placating them in whatever way necessary.
In his line of work, he's found that plague demons are the more reasonable of the threats. Although they bring about countless deaths if left unwatched, in secluded places they do little more than play and cause the occasional cold in rats.
You are one such demon, living in the burnt remnants of the village you were born in. The deaths have long since passed, yet you persist on the rodents who still thrive in the ruins.
He pays you a visit regularly, making sure you don't start to wander. Whether that means playing your games or simply listening to your stories, he doesn't care. All he cares about is that you stay put.
He keeps his mask in place, peering through the fog and thick glass to find your figure.
Then he hears the snap of old wood, and turns to find you in the ruins of a shop, the building rotted and falling apart from time and the fire that cleansed your arrival.
"Ah, there you are." His voice is muffled by the mask as he approaches, stopping several paces from you.
