Where was I? | Dark Souls - Part 29

It's been 2 weeks since I last played but I remembered what I was doing pretty quickly. Realizing where I was, I continued to explore the Duke's Archives until I found my way to the Crystal Cave. After that, I decided to go side-questing to help Siegmeyer of Catarina and ultimately free his daughter Sieglinde of Catarina from the Golden Crystal Golem.
