So I first encountered the word three days ago - I decided to make my way through the Baldur's Gate series and started with The Black Pits, where it's mentioned. I'm aware of the psychological phenomenon where you start seeing a word or concept you recently learnt about everywhere but man, still feels like a huge coincidence.
So anyway the pronunciation- ge- same as in "get", -as same as "us". My native Czech has super consistent rules of pronunciation, with each letter always representing exactly one specific sound (well, almost always) and it works out like this.
