Okay. So, the PCs went into the Tomb of the Primes, and discovered that Sentinel’s grave is empty. When Firestorm brought the journal close to the casket, it projected a hologram that Sentinel had recorded during the Great War that was meant to explain why he disappeared twenty million years ago. Axis then tried to speak to Sentinel through the Matrix, but something in the Tomb has instead caused the spirits of all the Primes to appear briefly. Axis has been convincing Sentinel to tell the PCs what he’s hidden and where they can go to find it, while Firestorm and LD-L1 are currently speaking with the other Primes to see if they know anything else.
Another thing to note is that, before Sentinel’s journal played its holographic message, it displayed an emblem depicting a European-style shortsword and a lantern both inside a wreath of flowers, along with the sentence “The Sentinel’s watch is not yet ended” written in English.
I was thinking that Trion could do some Space Magic and download some lost records or old theological texts onto the disk, which might be of interest to the Followers (and maybe to the PCs, too).
