Ra’s Evil Grin challenges adventurers of at least 11th level who are seeking a powerful magic item—the globe of Arden. If a different item suits your campaign better, another appropriate powerful item can be substituted as the final objective. This dungeon culminates in a battle with Dendorandra, a lesser marilith known as a dark daughter. As a lead-in to this adventure, the GM may use a map from another treasure hoard showing the location of the globe (detailed more fully in “The Legend of the Globe of Arden,” below) or a priestly tome describing Arden, the long-dead avatar of Ra, and the wondrous powers of an unknown artifact called the globe of Arden. Such a tome might mention that the globe emits rays as intense as those of the sun, destroying all they touch. In any event, characters should need to consult with sages and oracles to determine the location and history of the globe and dungeon. A sage could also provide a map to the dungeon’s location, referenced in the “The Legend of the Globe of Arden,” below. We set the dungeon on a small, remote island far across the sea, but you can relocate it to suit your campaign. This dungeon provides numerous puzzles, a few traps, and only two monsters. Those monsters, though few in number, should challenge and threaten even the most combat-hardened party—particularly after the party encounters all the vicious creatures that inhabit the Island of the Globe.
