This is our 54th installment of the one-page dungeon series. The objective is to create self-contained adventures/dungeons with all things necessary to spawn fun adventures on a single page. It is system-neutral so it can be easily ported to any system. It shouldn’t be much trouble to include it in any medieval setting. This one is about a marvelous, extraplanar dungeon filled with treasure. After visitors leave, the Vault of Sapphire resets itself and teleports to a new location in the multiverse.
