Samarach is a nation on the Chultan Peninsula, and is virtually unexplored by people from the civilized lands since it is incredibly difficult to reach. It is surrounded by rugged mountains and to the west are the Jungles of Chult. Tashalarans describe Samarachians as cowards who barricade themselves in walled cities at night. The natives apparently cloak the paths to their cities and the passes through the mountains with illusions.
Samarach will be featured in the upcoming Storm of Zehir expansion pack, described as a "xenophobic jungle nation" in an associated press release.
