There's no connection other than them both being sexy vampire investigators with a name that begins with F.

Fabien is the Malkavian detective from Bloodlines 2. Fennorian is the vampire investigator of House Ravenwatch in Elder Scrolls Online.

I'm loving what they did with Fabien's character.

Hope Fennorian doesn't get jealous.

There's a 2 hour gameplay video by theradbrad showing the beginning of the game and while it's not the immersive sim that the original was, I already know Bloodlines 2 will be my game of the year. It looks like an incredibly fun action rpg.
