The Player is keenly aware something is not right when
entering Irithyll of the Boreal Valley. While other areas have had watchdogs
and gatekeepers barring entry prior (Vordt and the minor Outrider Knight, Iudex
Gundyr, Wolnir), this was the only one with an actual barrier. The Small Doll and conquering/
running away from the Sulyvahn Beast are necessary to enter Irithyll. Someone
doesn’t wantyou coming in and discovering whatever it is they have. And
soon we learn why. This isn’t just Irithyll of the Boreal Valley. It’s Anor
Londo, the City of Gods. And it’s been overrun with malice.
