"I have come like this in your form, so that you may understand my presence. Perfection is absolute. You must be made perfect..."

Inspired by the Space:1999 season 1 episode of the same name. The associated character was portrayed by Catherine Schell, who later went on to play the shape-shifting alien character Maya in season 2.
Yes, technically this is the Servant of the Guardian from the episode, but I'm invoking "Artistic License" and "Rule of Cool".

Digitally created in Krita. After battling with creating my own Pirian landscape and getting unsatisfactory results, I took a screen-capture from the episode and ran it through some filters as well as adding other colour elements.
