Fabula means "Story", "Fable", etc.
Mag
nus (emphasis on there being an N

) means "Great" but you'd probably want to use "Magnis" instead, it makes more sense.
and Crystallis isn't actually latin, but a latinized word from "Crystal" meaning "Of the crystal"
Fabula magnis crystallis:
Tale of the great crystal
Fabula magnus crystallis doesn't make any sense, because you've got an adjective that doesn't match either of the two nouns
Fabula magna crystallis Great tale of the Crystal

No, I'm sorry but that's all wrong.
Crystallum, i is a latin word indeed, meaning a crystal, a gem or even ice.
Crystallis does not mean "of the crystal", that would be
crystalli (genitive case, singular form).
"Tale of the great crystal" could be translated into "Fabula magni crystalli".
