   Summary

   After Regulus reaches past his 'expiry age' according to pureblood society, and with no marital prospects left except for the opportunists looking to take advantage of the Black family's predicament, he is allowed to marry James on the condition that Regulus will conceive an heir no matter what it costs and that James will move in to live with him into Grimmauld Place.

   James follows him into the imperial Black family to protect him.
