"[after retrieving red pages from the other four Ages of Myst] Ah, you've finally returned. I owe you a debt of gratitude, for you have nearly released me. My name is Sirrus. I trust that from your explorations, you've become convinced that my wicked brother Achenar is guilty, and I am innocent. It is I who am wrongfully imprisoned here, imprisoned by my father. I don't know who you are, or how you came to this island, but I assume you must at least know something of the books. It was Father who was a master of the books. He wrote hundreds of them, all describing and linking to the fantastic places and Ages which he had discovered. The room in which you now stand was our father's library. It was here in this room, on this island named Myst, that he housed most of his books. But such a waste... by now, you have surely discovered that Achenar has burnt and mutilated most of his books. Why? Our father was always watchful of our explorations. We grew up under his strict supervision. But when we came of age, he gave us unbridled access to the Myst books. He began to leave our adventures more and more unchecked. Unsupervised as we were, my brother began to become... disturbed. He began to take more from the Myst Ages than he had given. Soon he gained a twisted... pleasure... from the conquest and destruction of the other Ages. It was horrific. His thirst for destruction, alas, even I discovered his insanity too late. He had completely destroyed all of the Myst Ages but four. I wasted no time; in warning my father, I thought he would recognize Achenar's guilt. But in a fit of rage, he imprisoned both my brother and myself within the pages of these books, designed to hold us until he could judge which of us was guilty. To discover the truth, our father embarked on one final journey. However, he has never returned. I can only assume that he perished along the way, leaving me, an innocent victim, trapped forever. But now, you are here to release me. Listen carefully. You must find one more page, and I will be forever free. There is a book on the shelves in this library, which is mostly burned, but has a few pages still intact. It is the last book on the middle shelf. Find it. This book is filled with a variety of patterns. Find pattern 158 and recreate it on the door of the fireplace. This will bring you to the last red page. Bring that page to me, and I will finally be released, and able to reward you, of course. Ignore the blue page. That page finishes my brother's book. It chills me to even think of what would happen if you were to release him. There is another warning: Where the red and blue pages reside, there is also a green book. If you touch the green book, you will also be imprisoned forever. Our father gave us this same warning long ago. I suggest you follow his advice. Go now. Soon we will meet face-to-face."
