Correctly understood, numinous is the unity beyond our perception of its two apparent aspects; aspects expressed by the Greek usage of ἅγιος which could be understood in a good (light) way as 'sacred', revered, of astonishing beauty; and in a bad (dark) way as redolent of the gods/wyrd/the fates/morai in these sense of the retributive or (more often) their balancing power/powers and thus giving rise to mortal 'awe' since such a restoration of the natural balance often involved or required the death (and sometimes the 'sacrifice') of mortals. It is the numinous – in its apparent duality, and as a manifestation of a restoration of the natural, divine, balance – which is evident in much of Greek tragedy, from the Agamemnon of Aeschylus (and the Orestia in general) to the Antigone and the Oedipus Tyrannus of Sophocles. Knowing this apparent duality and explaination do you still want to be Sinister and such?
