Eclipse

You create a 15-foot-radius and 60-foot-high cylinder of magical warding energy. Centered at a point within range you plunge the Stone tool into the ground and imbue the dark power into the area around you and any creature you choose at the time of casting. To an outside observer, all terrain within the area appears undisturbed and those within disappear from sight. Inside the area becomes shaded in dim light and the wind no longer affects the occupants.

For the duration any creature inside the area cannot be detected by magical means such as Divine Sense, True Sight, Detect Thoughts, or Find Person. In addition, the caster may focus the power of the wards on a creature within 120ft of the Eclipse's edge, forcing it to make an Intelligence Saving throw. On a failure, the creature cannot detect the wards through natural sense in addition to magical, on a success they are unaffected.

Creatures cannot teleport into the space, and any warded creature who leaves the area will not be able to enter again unless the spell is cast again. If cast in the same area for 1 week straight, the effect becomes permanent. 

Each Spell slot above 5th level enables a size increase of the warded area: +15ft to the radius, +30ft to the height.
