I actually heard a theory and forgive me but i really do not know from where that the excalibur umbra is the result of the warframes that did not phaseinto the second dreamand instead stayed behind to protect the others. I think it was StallordHQ from youtube but i would like to stick with that theory as to the reason why they are called shadow. Their sacrifice went unnoticed and since they didn't go into the second dream they have even more blood on their hands defining their 'evil' nature.
