Road

Roads appear in nearly every Zelda game, but they only play a role in Zelda II: The Adventure of Link and The Legend of Zelda: Ocarina of Time. They connect the various towns and other important locations in Hyrule, as just about any roads do.

The Adventure of Link
Roads in The Adventure of Link are simply plain, light brown spaces in the overworld. If Link stayed on the road, enemy silhouettes would not appear. If Link strayed from the road, enemy silhouettes would appear and make chase. If Link returned to the road when they caught up to him, there will be no enemies in the battle screen, just a desert-like background. Fairies, however, could still be encountered on road spaces.

Ocarina of Time
The function of roads in The Adventure of Link makes a cameo in Ocarina of Time. If Young Link wandered around Hyrule Field at night, skeletal Stalchildren would appear from the ground and attack him. However, if he stayed on the dirt roads that crisscrossed the field, the Stalchildren would not appear.
