"The final distinguishing feature of Cypher is his sword. It is a mysterious weapon that he has never been seen to draw on the battlefield, though rumours surround it: it is an artifacts of the Dark Angels; it is the Lion Sword; it is broken; Cypher seeks to reforge it and present it to the Emperor of Mankind, obtaining absolution and forgiveness. "
The sword also look similar to the one on the Cypher model.
My theory is that the old man is the previous Cypher, or at least some form of psychic remain of him.
I would find hard to imagine him being physically present, but if he is some kind of psionic projection or psychic ghost/memory linked to Zael, it makes more sense and justify him appearring to Zael alone.
I mean I do not think I posted a reply yet but this comic has gotten better and better....and I can say this as I have been reading since the first episode...ok I think you were about 5 in but still..haha
So he need two pistols now...
As far i know the Cypher thing is a position in the church not a person "per se"... So he is going to be the next Cypher... ALSO, Cypher is always alone, so he will leave the Ttaus and the Elves to fulfill his path...
