Wanderer

Wanderers are individuals that came to the world from various game worlds.

Overview
The Dragonlord Villers Film described Wanderers as "People who come from somewhere else." He notes that form time to time, even people of unknown species appear.

The most notable Wanderers are:
 * Arc
 * Hanzo
 * Thanatos Sylvius Hilk

Time Difference
Hanzo was the founder of the Great Canada Forest, giving it its name as well as the City name Maple. However, Hanzo was in the world 600 years ago.
 * 600 years ago, the name Canada and its national emblem the Maple leaf did not exist. Those are fairly modern day.

This means between Hanzo the Wander's presence 600 years ago as a likely modern gamer and Arc's presence now as a  modern gamer, time appears to have distorted.
 * Hanzo is very likely a reference to the legendary ninja Hattori Hanzō.
 * This opinion is bolstered by the fact that Arc himself was a Japanese gamer from the modern age

A guess would be for every 200-600 years in the World, 1 year passes on the Earth,
