When the demon realm in Britain caught on fire in 1432, the purple demon's perished. The remaining two were a young couple. The male was the son of the Purple Demon King. His name was Vincent. He fell in love with a peasant demon Named Violet. The two were going to have  baby soon..one of a new breed..but before the baby was born, the fire had hit them.

"I can't..breathe V-vincent.." Violet chokes on the smoke

"N-no..we'll get out..we'll have our son! we'll...we'll----"

"Vince....Listen....were both going to die....so please..promise me..we will find eachother..and make everyone suffer.." 

Vincent was crying as he nodded...

Then the two were burned alive..and the baby was gone
