The funerary mask they recovered in Wati, known only to them as the Mask of the Forgotten Pharaoh actually belonged to Sky Pharaoh Hakotep I, who ruled Osirion during the Second Age over six thousand years ago. References to Hakotep as the Sky Pharaoh recounted his ability to 'ride the stars by night'. Thanks to a few other obscure clues in the library, combined with their knowledge of history and the arcane, the party suspected this might refer to magic once possessed by the Shory, an ancient people said to have created great cities that flew through the skies thousands of years ago.
The hidden Spiral Archive library revealed that Hakotep was involved in some ancient war, and he was convinced that an attack was coming from enemies who 'lived in cities in the clouds' - further solidifying the idea of Shory involvement. Apparently the Sky Pharaoh was seeking to find a powerful weapon to defeat his enemy, and there was evidence that he actually found this weapon - but the only details the party found were the remains of papyrus scraps depicting confusing geometrical patterns.
A scroll was found describing Hakotep's tomb as 'having wings', part of the confession of a member of a group called the Sacrosanct Order of the Blue Feather, which also claimed that the Sky Pharaoh's heart and funerary mask were stolen from his tomb before it was 'lost to the skies'. This document indicated that these two items possessed pieces of Hakotep's soul, which were separated from his physical body. Hakotep's successor, Pharaoh Djederet II, ordered that members of this order were to be rounded up and questioned - but those scrolls were to be found in yet another secret library known as the Dark Depository.
Having now found this second library, the adventurers have yet to find these Scrolls of Inquiry as they were called, but they located the journal of a Priest of Nethys who was either a member of the Sacrosanct Order of the Blue Feather or doing very similar research. The priest's name was Khnenti, and he was apparently obsessed with the mystery of the Sky Pharaoh. Khnenti wrote extensively about the funerary mask of Hakotep I, and that it also contains a portion of the Sky Pharaoh's soul, specifically his ka, which apparently fuels the magical abilities of the mask. It was also noted during their search of the room that all of the sarcophagi in the chamber they're resting in contain the remains of those that were being punished by being embalmed and mummified while still alive for various crimes involving the search for knowledge that had been deemed as protected by order of the pharaoh. And, in fact, the occupant of one of these sarcophagi was none other than Khnenti himself - a contemporary of Pharaoh Djederet II and apparently during the time period when the Scrolls of Inquiry were purportedly written.
It is apparent to the party that these scrolls, and perhaps more information, are still to be found somewhere in the Dark Depository - perhaps in one of the other rooms they've yet to explore. As well, they hope to find the location of this Vault of Hidden Wisdom, where Khnenti indicated he stored his most precious research on Hakotep, including the Sky Pharaoh's 'darkest secrets'...
It takes several hours to go through everything, and truly the adventurers have no clue as to what time it us in the world outside of this ancient library by the time they've gleaned everything available. In fact, they're fairly certain that there isn't any more to learn in this particular place. Their research has finally revealed the Scrolls of Inquiry, found in this very chamber. The scrolls are cumbersome and difficult to read, and most of the confessions recorded upon them are of no use to them. One transcript, however, does contain some useful information (OOC - see Player Handout #2 in the Google Slides below for details). After hearing the others tell of this, Devin realizes he may have heard something about that. The half-orc bard recalls he heard some months earlier. The story went that an important and high-ranking priestess of Nethys was said to have discovered an artifact of some kind beneath Azghaad's Spire in Sothis. Her name, as he recalls, was Serethet - and soon after the discovery that had all the treasure hunters and nobility in the capital city of Osirion buzzing with excitement, the priestess disappeared. There were rumors that she had fled Sothis after being summoned to an audience with the Ruby Prince himself.
Besides the grim contents of the scrolls, the party also discovered a collection of architectural plans detailing a series of tomb designs of incredible complexity. Each plan is labeled with a double hieroglyph of an owl inside a house. It didn't take long to cross reference the hieroglyph as the signature of a very famous architect from the First Age of Osirion, a talented man called Chisisek. There is also a note mentioning a meeting between Chisisek and the Sky Pharaoh, but nothing more is found on this topic here. It appears that the interred priest Khnenti possessed further research on Hakotep and the architect both, but these can only be found in the Vault of Hidden Wisdom. The location of the Vault is secret, but there is a notable clue that "worthy scholars can find the entrance by casting their eyes from the summit of the Tower of Ra’s Glory at dawn on midsummer’s day." Of course, it seems likely to Francis that casting Speak with Dead might make their efforts much easier than that...
Getting ready for his attempt to communicate with Khenti, Francis firsts casts Comprehend Languages, then casts Speak with Dead. "How would I find the Vault of Hidden Wisdom?" The corpse rises in response to Francis' spellcasting, gazing at the cleric with empty eyes as he asks his question. The voice of the corpse is like the fetid stench released from a deep grave as it responds. "Seek the Vault of Hidden Wisdom where the shadow's tip of the Tower of Ra's Glory touches the land as the sun rises on midsummer's day."
He considers the other things that they wanted to know. Maybe.... "Why is the Temple of Nethys hiding information about Hakotep?" Again, the sepulchral voice speaks its answer to Francis' query. "The Sacrosanct Order of the Blue Feather, a sect of the Temple of Nethys, sought to learn the secrets held by Sky Pharaoh Hakotep I, where he lay interred in his tomb. But the knowledge they gleaned was deemed too dangerous by Pharaoh Djederet II and the Order was charged with keeping it secret from all except themselves. For not even the Pharaoh, himself a worshipper of Nethys, would see valuable knowledge destroyed."
Francis asks "Where is Chisiek buried?" Again the raspy voice of the long-dead scholar speaks in answer to Francis' question. "Chisiek's tomb lies in the Parched Dunes, north of the source of the Crook River in the foothills of the Barrier Wall within a steep-sided ravine at the western edge of a valley hidden from those that are not seeking it carefully." The cleric is struck by the preciseness of the answer, and is not surprised when the corpse's empty eyes seem to bore into his own as it surprisingly continues to speak briefly, apparently in an addendum to its final answer. "Find the tomb of the architect who built the Sky Pharaoh's sacred pyramid. Finish my work!" And then the corpse seems to groan as it falls back into its crypt.
