From the publisher's website:
“Death in the Pincers” is a short adventure for five 1st-level characters that takes place in the Chaos Scar, near the King’s Wall. It starts as a fight with drakes modified by a Chaos Shard, turns into a battle in the middle of shifting magical terrain against giant ants that are trying to steal the drakes’ treasure-laden bodies, and ends with a second battle against giant ants fixated on eating the characters instead of the drakes.
If you’re not playing a Chaos Scar campaign, you can still use this
adventure by integrating it into any existing campaign situated near a wilderness area that had mining operations at some point in the past. Unlike some Chaos Scar adventures, it features a great deal of interaction with an active chunk of the meteor. If you use the adventure somewhere other than the Chaos Scar, you’ll want to invent your own explanation for the meteorite’s magic.
