You bind shadow material into an enchanted fey road, fixing its path between two points so as to hold against ordinary weather and mundane alteration and to stretch and bend in shadow tides. This is called a shadow road, and it is subject to normal wear, to destruction by those with the tools to break it, and to magical destruction by hostile forces, such as by Dispel Magic.   If you wish, the spell may include a prayer or offering that serves as a keyword. This secret of the road allows anyone who knows and uses it to add one or two effects to the road, such as faster travel on the road (up to double the overland speed usually permitted) or locking and unlocking the road’s portals outside of the Shadow Realm. Those who do not know the prayer, ritual, or offering cannot enter the road from outside of the Shadow Realm.
