You've got me all wrong, Rune. 

I only meant that the firey energy came into contact with Wiri and it reacted to that in the way described. I did not mean to give the impression that Wiri did anything. 

Akhen sent his spiritual fire into the world, just as Mellivora sent her love. But the spiritual fire reacted to the love by creating lust, etc. And the it reacted to Wiri by creating it's own subteranean moisture network. But that turned out to be Lava. Because it's spiritual fire.
