Alacritis is expanding... again!

Name: Swallet Ring
Description: At the shoreline, there is a shape that juts out of the land. A short, but wide, bridge connects the mainland to a great circle of land in the ocean. The circle is merely an outline, filled in the middle with salt water. There is a small break in it at the bridge to allow fish to come in and out, but they are much easier to catch in the shallows within the ring. The water just off the inside edge is, indeed, quite shallow, reaching only the knees of an average-sized wolf for a few yards. At the end of the shallows is a sudden drop-off, a sinkhole hundreds of feet deep. The ring can be a peaceful place to rest and a convenient place to fish or cool off, but one must be careful not to be stranded in the deep.
REFERENCE because I suck at describing things right now.
