Since i work as a junior engineer on Thebes , i have been observing the minefield in the Wall of Seth for quite some time now." He made a short pause , unsure how to proceed further.

But the gravitational pull of our sun and planets do indeed degrade the integrity of the mine field." He reached into his pocked and took out a folded peace of paper.
