@Saltypatra's next video could be just her running through the entire deck of troops saying each name...
But jokes aside, with my background in English-speaking fantasy literature and studying Latin in my youth, it's fairly easy to help you with the intended pronunciation:
Stryx is derived from the Latin genus for some owls, and so is pronounced the same way: striks
Sylvanimora is Latin for "delay of the woods": sil-van-ee-mohr-ah
Emperor Khorvash is presumably standard fantasy name pronunciation: kohr-vash
Feel free to post any other names you have trouble with and I'm happy to have a go. Either I'm right or one of the devs might come past and correct me - win-win!
