The town of Rosehaven was a fairly quaint halfling village that had a large amount of wheat farms. 3 miles away lies a large volcano that a half dragon tyrannosaurus rex calls it's lair. For around thirty years the Scarlet Menace was a local tyrant. Wandering and stealing the spoils of bandits and merchant caravans. Forming a massive horde within their lair it became a local legend of the spoils within.
One day a young mother had fallen ill, their young daughter was desperate to find a method to buy the medicine needed to save their mother. Managing to steal only enough in the lair to buy a medicine they hoped the Scarlet Menace wouldn't know. Unfortunately, he did.
The volcano erupted with the enraged roar of the half dragon. Screams of rage and unbridled fury came out like thunder. Enraged at someone even so much as touching their lair the Scarlet Menace turned on Rosehaven, striking it periodically as just a form of malice. The town could never form anyway to actually stop them, their only solution was to pray for someone to be able to thwart this monster.
