Lempo :3 Lemme make a big post about him
From Christianity's perspective Lempo is akin to the Devil.
That's true, as Lempo is the worse half of two deities in folklore:
Lempo goes hand in hand with the name Lempi.
As a word "lempi" means passion, attraction and goodwill.
Lempi is the goddess of fire and love.
Lempi could be a feminine gentle force, Lempo could be more a masculine force that acts on raw passion.
It could be that Lempo is Lempi corrupted, honest love gone bad by adultery.
So really, Lempo is all about R-18 stuff.
What comes to my use of Lempo in my story, YIH doesn't use his fertility aspect because it just has no place in it. Instead Lempo is a forest deity who guards the forests.
This isn't anyhow true to the 'source material'. His appearance in YIH is unique as a forest deity. But he definitely is of an "evil" alignment.
He shapeshifts to deceive, he's the son of the mother of diseases. He's worked with his mother to further her plans for a while. Then he turned coat on his own family. On paper, he's a thoroughly bad agent.
But after turning his boat, he's the only one to possibly undo the destruction his mother has done.
so he's a bad boy gone good. :>
