You had a rather loverly comment until you mentioned the "<lala> ass *skull*ed up sign".

By the way, unless your sig is some sort of joke I don't get, the word is "perfected", not "prefected". However if you did goof, I shall enjoy this moment of irony.

*enjoys*

All right, now then, it's not a summon, it's not from materia, it's not a limit; what it is is Jenova's supreme powers of illusion channeling through Sephi. Recall where it was talked about that she "showed the ancients their dead" all Jenova's power of illusion. Jenova is a master illusionist, and was giving that power to Sephi, who utilized it. If an illusion is powerful enough, it CAN hurt a person.

So there. 'ave that then.
