The Day of Impending Battle

Several miles deep inside the Great Ashfallen Forest, the enormous dimensional crack was revealed, towering over even the tallest ash-grey trees like a colossal titan.

Unlike normal spatial gateways, where passing through them would take one from Point A to Point B, the dimensional crack didn't look much different from a shattered glass mirror leading to a mirror dimension.

Except, it wasn't the mirror dimension; it was the Gehenna Realm, a small part of Chaos.

A person does not travel from Point A to Point B by passing through the dimensional crack in the normal sense.

Spatial teleportation at least involved covering much more distances than the steps actually taken to pass between two points. On the other hand, such a thing didn't exist when entering Gehenna; the distance taken to enter Gehenna was the same distance actually traveled.
