The Clamp-Fanverse

This is a 99% of the time a CLAMP blog, and because their universe is so big, how can anyone be bored?
CLAMP is a group of four mangaka that have been creating manga, anime, movies, and more for over 25 years. The worlds of their stories combine in multiple ways, and thus fans call this the "CLAMP-verse".
I have read and am a fan of all of their manga, especially CardCaptor Sakura, X 1999, and Tsubasa Reservoir Chronicles. I strongly recommend trying a Clamp series if you don't know anything about them.
You can ask me anything concerning themes, similarities, connections, ships, characters, topic-related questions, or anything you can think of. I dig that stuff.
Enjoy, fellow CLAMP fans! :)
