Dark Souls Remastered | Hidden Daughter of Chaos chamber, then Demon Ruins

After ringing the Second Bell of Awakening, I make my way to the Daughter of Chaos chamber, hidden behind an illusory wall. I talk to Engyi, rest at the bonfire, and interact with the Fair Lady (Daughter of Chaos), joining the Chaos Servant covenant (which grants a Steam achievement). From there, I continue to the Demon Ruins and reach the first bonfire there.
