Spriggans and Demons

So I know our sites plot line mentions the spriggon. Is it possible to have ties to them? Perhaps one day become one? Same question for demons. Will it ever be possible to undergo the procedure to become a demon of the book of zeref? I understand both these things are large concepts and would need a much more active and populated site to sustain but just curious to see where my characters potential plot will go.

I think it would be possible but we'd have to wait for Brandish to reply.
