[Cimon Morpheus]:
To be a Primordial Spawn was rare enough, but to be the son of Hypnos, primordial lord of slumber, and a descendent of Morpheus, the god of dreams, as well? That should be a feat in some record book somewhere, if you asked Cimon.
House Morpheus are said to be descended from Hypnos, and, while in a way, that is true, the full truth was they were descended from his son, Morpheus, the god of dreams himself. No matter how you argue it, Morpheus was their family progenitor. It was why their family name was 'Morpheus.'
House Morpheus, like many noble houses, has their own secrets in which they guard, especially when it comes to cultivation. For their lucky few, this secret is called the 'Sleeping Realm,' where their Progenitor dwells.
