I imagined fearfully and swallowed. Breathe underground I don't know how.

- Land? Sand, which is oxygen. Organic, making the ground black, which also has oxygen, the other gases of the air and whatnot... If using the skills of transmutation, decomposed into component parts sand and humus to be... what? A hole in the ground and the ability to breathe? - looked up at Sean.
- Well, I see you're ready! Buried?
Who came in ten minutes Lord of Ordinarily caught Sean, trampling on my grave, and gladly took part in ritual dances. Grrrr! Here trous - bury both!
