If you wanna discuss Sligs I'm your man. You should check out my role play
A Slig Who Cares. The fic focuses on a Slig that goes by the name Ugai. He explores Mudos in search of his true purpose.
As for the ways Sligs are in Industrial settings I also believe it it the from the way they were raised. Born with a nurturing nature I bet they could of developed to be much more if it wasn't for their cruel, abusive mothers.
