The island is one contiguous landmass in the style of the Azura's Coast region, with lots of rocks and a shallow coastline. The two points of interest are a Legion fort with a small fishing hut and dock, and a wrecked longship lodged in the reef right off the coast of a recently-abandoned Nord cave hideout. The Legion fort uses vanilla set content and the hideout/shipwreck uses T_Sky* content.
The island can be reached by coc'ing to "Showcase Island," "Showcase Island, Legion Fort" or "Showcase Island, Nord Shipwreck."
Thank you!
