After 7 days of wandering in these sere dunes, our wineskins are depleted. At night we had dug furrows to escape the radiant heat trapped in the sands. Now, at this crossroads, we are without our guide, and the naked sun exacts its mortal tithe. But there, in the distance: an onyx monolith, blazoned with a dark bolt! The enchanted vessel held 12 ounces of lifegiving elixir, and could keep it cool for 24 hours, or hot for 12. We were saved.
