West's Notes on the Tomb of Acastus

Credit to: Westen Lancaster 
OK. We’ve found the Vault of Acastus. That was much more dramatic than I expected. It looks like we’ll be able to explore the vault in a couple of weeks, so we need to get ready.
Meanwhile, there are a few things to consider. The tower is huge, and coursing with prima materia. That means everyone will be heading for it. The duregar will want the prima materia. The dragon Arva and most everyone else will want the treasure. We should send some people to just guard it until we can mount the expedition inside.
The vault was hidden after the war with the Midnight Legion. It’s possible some vampires are imprisoned inside. There could be any manner of other monsters guarding it, as well as traps and mechanical guardians. With the prima materia powering it there could be anything, so we’ll need to be ready.
