I used to use Ladul quite often, as that's what everyone else used. One day I decided to google it out of curiosity, and naturally, nothing came up. Then it struck me: It's Iadul, not ladul. It made way more sense (particularly the latin root of Romanian) and the moment I googled it, this came up:
To be honest, I wasn't sure if it was a Ravenloft-canon bastardization (as in the Ravenloft writers screwed up), or if we were just DOING IT WRONG
The funny thing is, after I switched to "Iadul," people started to 'correct' me
