I have been compiling information on transmutation circles...they seem to keep popping up everywhere I look close enough and recently I have found another example.
|Howl's Moving Castle - Transmutation Circle|
It seems to me if these circles keep appearing across all sorts of different platforms...then possibly these symbols are the key to channeling the earths energy.
|Howls Moving Castle - Transmutation Circle|
This specific circles are not as detailed as the ones found in Full Metal Alchemist however if we look closely there are plenty of similarities to be found.
