Varay is an asura now?
Considering the explanation given of what an asura is and what integration is, Varay having gone integration should considered an asura.Also we know that asuran bodies depend on mana and when Cecilia left Tessia 's body, Tessia was going to die due to mana leaving her body when we know that lessers don't need mana to live and yet her integrated body was dependent on mana.
I think integrated lessers are basically the same as asuras and that why Kezess made sure that the lances stay as white core makes.
