PLEASE NOTE THAT THIS IS NOT A 100% SURE ITEM AND WE ARE NOT 100% SURE OF ITS USE, BUT THE USE IS WHAT IT IS IN THAUMCRAFT 2.
The Magic Carpet is an item that is in Thaumcraft 2. However, it is thought that the Magic Carpet is in Thaumcraft 3, since the config file has Magic Carpet listed in the entity IDs and you can find the Magic Carpet using inventory editors such as Too Many Items or Not Enough Items. You can sit in the Magic Carpet and you can fly it around, although it may not always work. fuck you theory
