So I just thought about an interesting potential interaction between Len and Enniya somewhere down the line.  So like, Enniya gets magic directly from her patron, yeah?  And Len eats a combination of metals and magical energy to fuel herself/in place of food.  Sure, she just eats surface thoughts and the energy that comes from them, but I'm just imagining her getting really hungry and not seeing anything else around, so she just decides to wait until Enniya gets done getting magic, and pounces on her to eat her out and get her dinner that way. =3=;
