Home of the Black Dragon in Chinese / Japanese...

黑龍之家 was added by special request of a customer. This phase is natural in Chinese, but it is not a common or ancient title.

The first character is black.
The second is dragon.
The third is a possessive modifier (like making “dragon” into “dragon's”).
The fourth character means home (but in some context can mean “family” - however, here it would generally be understood as “home”).
