Ulthar's Dreamland Location encounters are likely to grant talents. Investigators may also have General, Research and Gate encounters here.
Ulthar is a fictional city in Earth's Dreamlands described in HP Lovecraft's Dream Cycle stories.
The city is often characterized as being home to many cats, which inhabitants and guests are forbidden from harming. Ulthar's cats are intelligent and feature in many of the city's Dreamland Location encounters, in addition to several Gate encounters taking place in the dreamlands.
