I'll give you it.
In a time of science and magic, on the continent of Paiun, in the town of Coifall
A town primarily inhabited by seniors, and a few 4 or so families, the only young people in the village, finding them Selves one day bored, as young, intelligent people would do, they decided to summon some demons for a bit of fun.
bad plot, but hopefully will be fun.
basically this starts with the 12 to 16 year olds summoning the demons, and if it even gets there, maybe more plot will come.
Demons grocerylist of summoning
1x: human heart
2x salt boxes
1x troll guts
10x saliva of a goat
