Dylath-Leen's Dreamland Location encounters are likely to grant assets. Investigators may also have General, Research and Gate encounters here.
Dylath-Leen is a fictional location. It was a dark city of basalt in Earth's Dreamlands in HP Lovecraft's short story The Dream Quest of Unknown Kadath.
The city has a port from which black galleys travel to and from The Moon, explaining the ship connection between these locations. In The Dream Quest of Unknown Kadath Randolph Carter rides such a galley from the city to The Moon.
