When the heroes traveled toward the monastery of
Menthrop in the dark future in adventure
17-3 (The Honor and Oath) they found strange cave on mountains. Cave led to
a tomb which was empty. The heroes pondered the meaning of cave and tomb.
The tomb is a simple room with simple stone coffin drilled deep inside the
mountains. The heroes did not found anything else inside, but they were confused
for the marks on the floor and coffin.
