From HPL's either tedious (or fun YMMV) The Dream-Quest of Unknown Kadath:

"... Carter resolved to go with bold entreaty whither no man had gone before ..."

Dreamlands ... that Limnal Region. These are the dreams of Unknown Kadath, a non-euclidean journey to explore strange new vistas; to seek out squamous entities and eldritch civilizations: to go with bold entreaty whither no man had gone before.
