A fey individual from The Other Side of the Hill, Mister Springfield rescued some of the Heroes when they were beset by strange creatures while investigating Valos’ Tower. Mister Springfield brought them to his home and gave them rest before inviting them to dinner.
It was during this dinner that many things became clear. Mister Springfield and his friends were the last of an ancient race at war with The Goblini Empire. It was also revealed that he is Caelon’s father.
He has the ability to travel great distances through strange doors and a misty realm and whilst transporting the heroes, they strayed the path and wound up at Castle Perilous.
