Each map in the Astral Sea Beach set comes with and without grids. There are 16 different variations with Lighthouses, bare beach, a lonely island, rocky rapids, a ruin of columns, and dangerous red tides! There's also a version of open astral space, great for dream encounters or as a background for whatever you'd like to put on it.
"Some say that only spells of great power can take you to the Astral Sea, but if you know where to look, you may find it's shore hidden in your nightmares. There you can walk alongside waves leading to outer planes where gods and monsters dwell. The sand is white and made of crushed diamonds, the water warm and full of dreams. A Lighthouse sits on a promontory warning leviathans away from dangerous shores, and calling weary travelers home."
