Whispering Death Island

Geography
There is an image that appears on Hiccup's Race to the Edge Map. However, it is rather nondescript - brown with no indication of contour or vegetation. It does appear to have a number of coves or bays, with a very large circular bay on the Eastern side of the island.

Other Appearances
Whispering Death Island does appear on the Interactive Map on the Dragons: Race To the Edge website. The island thus far is not featured in this TV series, however.
