Jon Eddington was just a simple young dude fresh out of college when his grandfather, an archeologist named Jack, passed away. Jack leaves his New York house and everything in it to Jon, including an ancient Celtic pool he discovered long ago. One night, a strange storm blew in and Jon was blown into the mysterious pool and wakes up in a strange world known as Meridian. 

Things become more strange when a mark suddenly appears on his right palm; a triskelion. Stranger still was the power that the mark holds. Facing strange shadow-like creatures, the Mark gives Jon the power to vanquish them easily. Meeting a couple of pointed-eared soldiers Jon learns are called the Aelfar, they take him to a small industrial city of steampunk and smoke. Not knowing just what he was doing in the world of Meridian or why he was given the Mark, the answers all quickly become clear when he finds that he carries the Mark of the Hero. The mark also holds an omen of great calamity to come to Meridian. Jon finds that he was not the only human Hero to wear such mark but it doesn't bode well for him when he learns that none of the former heroes are alive and there's no way for him to learn how to harness the powers of the Mark. What's more, he must be the one to end the calamity and slay a Trith'ar witch before she conquers the world. 

Jon must bide his time and acclimate himself in a Victorian-Esque society he is sure are full of elves and dwarves while trying to prepare himself for what was to come.
