The Moor-Tomb Map - Dungeon Magazine 13

I mostly look for adventures with some urban elements to fit into the urban portions of Ptolus, but I am keeping an eye open for small dungeons to place beneath it as well. There are plenty of large dungeons available both as part of the Ptolus adventures and those that can be repurposed for use in Ptolus. I like to scatter about mini dungeons that can be quickly dealt with while pursuing other goals.

The Moor-Tomb Map contains just such a gem. Very little adjustment of the tomb itself is needed. Separate it from the rest of the adventure and slap it under some section of the city and presto, instant fun. You can even attach some criminals to the tail end of it that have a deal with other under-city critters like ratlings or an unsavory group of Assarai (lizard folk), in place of the bandits from the original scenario.

Sticking with the treasure map idea, the PCs can discover a map while browsing the Delver's Guild files, that purports to show a hidden tomb not too far under Oldtown, maybe Citation Street. It could be put just about anywhere. Notes could indicate a failed attempt to gain entry, but no additional details.

The dungeon itself mostly consists of traps to overcome with the exception of one "inhabitant". A wizard was pursuing immortality, but not lichdom, and his plan backfired when a hireling brought the wrong kind of tomb guardian to protect the place. The wizard is now mixed with the guardian, losing his spellcasting ability, but making the guardian tougher.

One of the traps in the dungeon could possibly knock the entire party unconscious resulting in the criminals pulling them from the tomb as prisoners. They would be considered for possible ransom or maybe for ratling food as payment for ratling services. If the characters have anything identifying them as allies or friends of important people then ransoming is guaranteed, otherwise the PCs need to do some talking. In the event the party was split then perhaps the others can try to free them or pay the ransom.

The adventure it comes from is geared more toward lower level characters, but the treasure is quite respectable. It wouldn't be hard to adjust it for higher level characters should you need a quick one for a mid-level party.
