Under a small timespan of a mere day, the allied nations that were hidden from the high-rank Supernatural races decided to come out into the light with a proposal to Dargena City's gate, asking for vassalage directly to Rex himself.
It came as a shock as Rex had never planned to create an empire.
He did want to make a nation where Supernaturals and Humans could co-exist but not to this extent. But then again, Rex knew that if he wanted something—then he must be prepared for the unforeseen effects that it would bring.
For, in this case, an empire is a natural progression of his sovereignty.
Discussing the matters with the others, and a solo contemplation, he came to a decision.
Rex decided to accept the proposal and establish an empire of his own.
Naming-wise for the empire, he had a few in mind but settled on the Clarentium Empire.
