It is a planet that does not rotate but is extremely close to the sun. One side is molten hot at 3,600 degrees and the other is 320 below zero. A bunch of white Necrofriggians colonist live there because the climate cannot bother them. They also guard the first quarter of the Map of Infinity in the temple, which is on the exact middle of the planet where temperature is about normal. The temple has a series of traps, preventing people from getting the first quarter of the Map of Infinity.
- The planet's name is a pun on the McDonald's McDLT, famous for coming in two halves, one hot, one cold.
