Infernal domain, Door of the Bravehearts

The whole world believed that there was only one entrance to the Infernal domain—the narrow Door of the Bravehearts. This was because entry from any other direction would cause one to fall into a maze and lose their sense of direction. Even if one could finally walk out of the maze, one would appear outside the Infernal domain and never inside.

The Door of the Bravehearts was the only entrance that would not lead to a maze. It was also the only entrance that connected the interior of the Infernal domain to its exterior.

And it was because of this that the Infernal domain was easily defendable. Even if one had a million-strong army, trying to gain entry through such a narrow entrance would only result in a battering by the armies guarding the Infernal domain.
