Acrophobia (ConceptTopic, 3)

From Compile Worlds

Acrophobia is the irrational extreme fear of heights. Blaze the Cat is quite famous for her acrophobia, but she better not fear, for she's not alone in that regard. Even then, she still keeps it a secret... kinda.

There's also this irony that one victim of acrophobia is also named after something that can fly. I dunno, but the world's just weird, in that way.
