He telleth her all the adventures until the time when he reconquered the castle that was his uncle's. He sojourned long time with his mother in the castle, and saw that the land was all assured and peaceable. He departed thence and took his leave, for he had not yet achieved all that he had to do. His mother remained long time, and his sister, at Camelot, and led a good life and a holy. The lady made make a chapel right rich about the sepulchre that lay between the forest and Camelot, and had it adorned of rich vestments, and stablished a chaplain that should sing mass there every day. Sithence then hath the place been so builded up as that there is an abbey there and folk of religion, and many bear witness that there it is still, right fair. Perceval was departed from Camelot and entered into the great forest, and so rode of a long while until he had left his mother's castle far behind, and came toward evening to the hold of a knight that was at the head of the forest. He harboured him therein, and the knight showed him much honour and made him be unarmed, and brought him a robe to do on. Perceval seeth that the knight is a right simple man, and that he sigheth from time to time. XII. "Sir," saith he, "Meseemeth you are not over joyous." "Certes, Sir," saith the knight, "I have no right to be, for a certain man slew mine own brother towards the Deep Forest not long since, and no right have I to be glad, for a worshipful man was he and a loyal." "Fair Sir," saith Perceval, "Know you who slew him?" "Fair Sir, it was one of Aristor's knights, for that he was sitting upon a horse that had been Aristor's, and whereon another knight had slain him, and a hermit had lent him to my brother for that the Red Knight's lion had maimed his own." Perceval was little glad of these tidings, for that he had sent him that had been slain on account of the horse. "Sir," saith Perceval, "Your brother had not deserved his death, methinketh, for it was not he that slew the knight." "No, Sir, I know it all of a truth, but another, that slew the Red Knight of the Deep Forest." Perceval was silent thereupon. He lay the night at the hostel and was harboured right well, and on the morrow departed when he had taken leave. He wandered until he came to a hermitage there where he heard mass. After the service, the hermit came unto him and said: "Sir," saith he, "In this forest are knights all armed that are keeping watch for the knight that slew Aristor and the Red Knight and his lion as well. Wherefore they meet no knight in this forest but they are minded to slay him for the knight that slew these twain." "Sir," saith Perceval, "God keep me from meeting such folk as would do me evil."
