What's your fear?

I'm not surprised...

medievalbellumophobia afraid of the medieval war
It'd be antiquabellaphobia or medievalwarphobia, you can't just have "medieval" be english and "bellum" be latin. And "ancient" is the closest meaning to "medieval," I believe. Also, the latin words in phobias often have a vowel attached to the end of it to make it sound better.
Sorry, couldn't help myself.
