I ran across this while digging through the wiki: a brief mention in Reign of Winter of a planet called Beurdreda, from the final book of the AP. It’s described as being an impossibly cold ice moon for some distant planet, inhabited by tunneling, three-armed humanoids.
Does anyone have any clue what’s up with this? Has anyone ever used this plot hook?
It's in the "Continuing the Campaign" portion of the book as one of the options for GMs to flesh-out and use as they want if they elect to continue the campaign using that particular thread.
The only thing you're missing from the description is that it orbits a vibrant, warm planet that's constantly washed over with Northern lights.
