Great hero

"Shadow Demons were locked away in this shady forest by a great hero long ago..."

- The Enchanted Earth loading screen

The great hero is an individual responsible for sealing away the Shadow Demons in their tomb in the Enchanted Earth. The identity of this individual is unknown.

King Peregrin
King Peregrin is credited with designing the impregnable box that the Shadow Demons were housed in. However, the source of this information is a history book whose truthfulness is questionable. Either way, Peregrin does not appear in the Hall of Heroes, so it is unlikely that he is the great hero.

Canny Tim
Canny Tim was present for the Battle of Gallowmere and if she survived, it is likely that she would be involved in its aftermath. A history book does report Canny Tim's death at the Battle of Gallowmere. However, the death described is the fate suffered by Sir Daniel Fortesque rather than Tim, calling the nature of the death, if not the death itself, into question. Canny Tim is also a member of the Hall of Heroes, thus satisfying the "hero" requirement.

Captain Fortesque
After the Battle of Gallowmere, Captain Fortesque is stuck in the body of his heroic future counterpart. What he does immediately following the battle is unknown, making his involvement with the sealing of the Shadow Demons a possibility.

Other Hero of the Hall
It is possible that another member of the Hall of Heroes is the great hero. However, it is unknown who among the heroes, other than Canny Tim, was alive and present in the late 13th century.
