Valley of the Damned

While casting this spell, you must keep your hands and/or spellcasting focus on the ground that you wish to open the portal from the entire time. If you remove your hands and/or focus from the ground, then the spell is cancelled and the spell slot wasted.

You open a permanent portal to a layer of the Abyss of your choice. The portal is 30 miles wide, and stretches forward from the caster until the it reaches the edge of the landmass that the spell has been casted from. Any creatures or structures that are on the landmass when the portal opens are sucked into the Abyss.
