Dimensional Gap

The , or Dimensional Crack, is an opening into the vacuum of time and space that separates dimensions. Such openings can only be created by beings of great power.

Traveling through the s has been found to distort time as some have reported 2 weeks elapsing in Jotunheim while 3 hours lapsed in Midgard.

Ragnarok Online
Since Midgard and Muspelheim are separate realms, it's implied that Surt had used a when he invaded Midgard during the Thousand-Year War. After being chased out of Midgard, Surt may have utilized a again in order to invade the realm only to be stopped and imprisoned by Thanatos. Once freed from his prison, Surt used the again to escape Midgard, except this time the gap remained open so Midgardian adventurers were able to pursue him.

Ending up in Jotunheim, Normans proceeded to establish a base camp and stabilize the that they came out of. With further research, they started using the as not only a portal between Midgard and Jotunheim, but also as a means to travel back in time through Midgard's history.

Ragnarok Online II
The Prontera knights and the magicians of Geffen's Magic Academy have been investigating the gap for a long time, but there does not seem to be any clear reason as to why the dimensional gap has occurred. After a gap opened in Payon Forest, another opened in the nearby Maple Forest.
