M. and thok letter (part 6) is a book obtained while training Dungeoneering as a reward for completing a dungeon which appears by the exit door after the boss monster is killed. It can also be obtained as a monster drop from any monster in Daemonheim. It, combined with the other parts of the book, make up the full tale of Marmaros and Thok's adventures throughout Daemonheim. Once the book has been obtained once it is impossible to obtain it again. However, it can still be read by talking to the Dungeoneering Tutor to view the Dungeon Journal along with all other texts obtained in Daemonheim.
Marm got stomped, but not so bad that he dead. I protected him best as I could, so please don't get mad at me. The big stomp creature so strong and fast, faster then Thok, but not as strong. I mashed up eels for Marm as they made me upchuk anyway. I hope Marm will leave and will write to you again. That always makes him feel better.
I can't hear the noisy feet of my friends above us anymore. Whoever at bottom of the dungeon is Thok's now.
Your older brother,Thok
