Argynvostholt is a location in Barovia. Once it was a mansion that served as home to The Order of the Silver Dragon, but has fallen into disrepair and ruin.
When the waffle crew traveled to Barovia's past, Strix made friends with the revenants of Argynvostholt. They traveled to the Amber Temple, made pacts with Zhudun the Corpse Star, and raised the dead members of the waffle crew. One revenant named Sir Godfrey accompanied Strix and the crew out of Barovia.
