Nabu the Wise - New History of the DC Universe

An Agent of Order, Nabu the Wise, first discovered the Reach infiltrator Khaji Da. Mistaking the alien artefact for a mystical talisman, he would sever the connection to the Reach, refashioning the sentient super-weapon into the Scarab of Kha-ef-re. 

He would use the Scarab during an ill-fated fight with the immortal, Vandal Savage. 

Badly wounded, Nabu sealed both himself and the Scarab within a pyramid in Chaldea's Valley of Ur. There he remained in a magical, restorative trance.
