Just curious, was the Diety you used for me, Khorus, a being of your own invention or does he actually exist somewhere?

Im currently building his domain and a religious structure around him, and I don't want to use a pre-existing entity if he's vastly different.

(Currently have his truest followers being like the old 3.5e Ravagers, which worshipped a similar god to how I'm writing up Khorus, who would rather bleed a victim slowly and inflict as much pain as they could instead of just kill them fast.)
