Talk:Warframe Lore - During the Old War/@comment-2001:A61:4809:D01:A8F7:ABB4:1095:596-20190402230703

"It is speculated that the Sentients would aquire Oro from Tenno. After defeating their Warframe and they would subsequently absorb the Tenno's Oro to give them the ability to withstand death."

The Sentients couldn't have gotten Oro from the Tenno, as only those already in posession of Oro can absorb another Oro. It's more likely that they gained some variation of it from their travel through the Void via the Solar Rails - just like the Tenno.
