I know, right?
So some of you may be unaware but the original IC reasoning behind the Conclave was that it was essentially an Imperium-wide Bulletin Board where different Inquisitors could post messages for each other and have conversations. Over time various non-Inquisitors gained access, and when we moved away from that first iteration of the Conclave, it became less of a messageboard and more of a freeform roleplaying space.
But that version of the IC Conclave never actually went away, it just wasn't referred to as much. Well, now that the OOC Conclave has been dormant for a long time, and the setting has moved on quite a bit, it seemed appropriate that the IC Conclave would also have fallen into disrepair. Thanks to the Great Rift and Indomitus Crusade timeskips, it has been centuries since there was any activity on the IC Conclave. Whole generations of Inquisitors have been raised knowing nothing about it, or knowing it only as a rumour or tale from some of their older peers
But the conclave wasn't just the ability to talk to each other, it's the archive of the stories that were told. And how valuable might all that information be? all it would take is finding an intact terminal and you could gather all that history, or perhaps revive the entire network...
