The Changed Verse

The Changed Verse is a shared universe spanning three fandoms. One day, the world goes through the Change, leaving chaos behind: people and animals transform — suddenly there are mermaids, centaurs, hell-dogs, mind-readers and pre-cogs, and everyone has to find their place in a world rewritten overnight. Each part below stands on its own, but together they map the same changed world across How I Met Your Mother, NCIS and House MD.
