Yes, you have come upon my most valuable
Runestones. These stones have been designed to be particularly receptive
to the game of Runestones.
This game is most popular, throughout Titan, due to the simplistic nature
of the rules. It is a somewhat dangerous game, but the prizes are high.
A rock is enchanted so that it will explode at some indefinite time.
Th participants, who are standing in a circle, then throw the rock to
each other around the circle until the rock explodes. The player holding
the stone when it explodes is out (if for no other reason than they
can no longer catch the rock given that there hands are either burnt
or missing)
