Tyrethali Ansrath is a very well-known level designer, one of the first, but less well-known as a member of the community. "Tyrethali Ansrath" is a pseudonym and his real name remains unknown. His levels generally stay within the very easy to medium-difficult range, often incorporating mazes, easy-to-navigate puzzles, invisible walls and other invisible obstacles, pictorial constructions including the CCLP2 level Spy, and very accessible construction. Because of this appealing nature, 32 of his 108 levels achieved spots in CCLP2, the most of any designer included in the set. Even though he hasn't made any levels since the release of CCLP2, his level Lazy Hourglass got into CCLP3. Tyrethali is currently tied with John Lewis for the highest number of levels contributed to both CCLP2 and CCLP
