W1F1 Says: Hello! This idea was... accidental, to say the least, and was literally born from a doodle of Terezi with draconic features on some math notes. The basis is a bit confusing, so I'll explain it a little bit here so you aren't completely lost. On a person's 13th birthday, or in the case of other species, the equivalent of it (Like a troll's 6th wriggling day), they become a fused existence typically based on personality, goals, or interests. Trolls are almost always fused with animals or mythological creatures, cherubs are almost always a personified version of a concept, and humans are usually either animal, mythological creature, or concept, but under rare circumstances, will not fuse or combine with an object! Earth and Alternia are also linked via magical portals that no one really knows the origins of, and new portals open and old ones close at random quite often.
I hope this makes sense! If you're still confused, just PM me please!
