Velavi
Creature 2Knowledge is power, and no one is more keenly aware of this truth than velavis. These scribes and junior scholars are tasked with maintaining the unfathomably vast collections in Stygia's Academies of Lies. Velavis are the front faces of the library, greeting visitors and determining whether to grant their requests. Their organizational skills are among the best in Hell, and their memories are long, allowing them to easily navigate their home library with astonishing speed. Velavis provide another vital service for Hell: should another devil make a valuable discovery, they're expected to report to an Academy to have a velavi record it on a scroll or book the velavi crafts out of living flesh.
Each velavi is intimately familiar with the collections in their library, and they have unfettered access to other Academies' archives. Those seeking information in Hell might be tempted to seek a velavi's aid, but the velavi will demand a high price before conceding any information—even then, the flow of knowledge almost always goes one way, as velavis are tricky with what they share. Librarian devils are custodians, gatekeepers, and guardians; it's exceedingly rare for velavis to share their knowledge with anyone but a devil of higher rank, and even then, it must be bought or threatened out of them.
