Mummy with lower half of body buried (HD 5, AC 5, eyes shoot 2 lasers, Save vs. Death Ray or take 5 dice of damage). It wears an emerald medallion (2000 GP). Quiescent unless the emerald medallion is disturbed. Two dead orange men lay nearby, one with a scorched hole blown in his head, the other with a scorched hole blown in his chest. 1-6 primitively armed Orange Men huddle at a safe distance discussing how to relieve the mummy of the medallion. They are not interested in treasure other than gems and technology, but will serve if offered such incentives.

The sword is -1 to hit, but +3 to hit vs. White Men.
