I don't believe so, no.<br/><br/>Mythic Greek origins would be perfectly fine, as well as putting you into the same hero family as Heracles of Greece.  Presumably, the artifacts were either handed down to you (apparently from divine heritage, since not all your powers are removable) or gifted as part of the war effort in the second world war.  (The gods are generally believed to have historically existed, but they don't tend to make themselves known much.)
