So lately when my friends and I finish a void run we're greated by a creepy transmition from an unknown Excaliber warframe. He doesn't say anything, he just stares at us while in the kneeling position, after about 10 seconds the transmition ends. I like to believe that this is Hayden personally, and that he's trapped in the void, but it's just a Head Cannon, does anyone actually know who this creepy dude is?
