These are player-facing articles, and thus I’ve chosen not to commit to things that players shouldn’t know about; beyond that, it’s ultimately up to the DM to decide what canon to use. So in the case of Sharn, the History section states “With that in mind, some people say there’s something strange about the Deneith enclave in Sharn; if you want to know more, check out Sharn: City of Towers.” This article establishes the exploration of psionics by the Sharn enclave; it’s up to the DM to decide if that study has a sinister origin. Likewise, regarding Shirin, that same section says “The Lord Commander of the Blademarks, Shirin Ravan d’Deneith, has such dreams. A recent convert to the Seeker faith, Shirin has been making contacts within the Order of the Emerald Claw and talking with Karrnathi warlords frustrated by Kaius III’s pursuit of peace; he may also be in contact with the Blades of Karrn in Stormreach, or Zorlan d’Cannith. Ultimately it’s up to the DM to decide if Shirin has enough support to actually move against Baron Brevan, or if his ambitions are far from being realized. A second question is whether Shirin envisions himself to be a second Karrn the Conqueror, establishing a resurgent Karrnath—or if his dream is to rally the Houses behind him in an echo of the War of the Mark, creating a realm governed by the Twelve.“
