The Path of the Fey Ones

When you cast this spell, specify a direction or destination within 50 miles. A portal then opens to a twilight road. The portal remains open for 1 minute, until 10 creatures step through it, or until you collapse it (no action required). This road extends infinitely and is in ideal condition. Your continued concentration allows you and those that entered through the portal to travel safely at a normal pace, but you can't rest on the road. If you stop for more than 10 minutes your concentration lapses and you are dumped back into your plane of origin at a random point within 10 miles of your starting point. Any creatures that wander from the path are deposited a random point within 50 miles of the casting.

After 3d4 hours of journeying the road, an exit portal forms leading to the destination chosen during casting, or 50 miles in a direction chosen when the spell was cast. The exit portal is invisible from the other side until a creature steps out of it. If you choose not to step through the exit within 10 minutes, any creatures you have conjured to the road are dumped back where the spell was cast. Travelers never incur exhaustion no matter how many hours they spent traveling the road. Each casting of The Path of the Fey Ones is likely on a new stretch of the infinite road, so if you leave something behind there you will likely never cross it again. 

A small chance exists that you encounter other travelers or monsters on the road, a chance that increases should you attempt to change your destination mid journey. Those not of fey ancestry may be tempted off the path by strange delights at the DM's discretion. The roll can be made with advantage if a guide other than the caster chooses to help keep them on task.
