How about

'Beyond Divinity: The Riftrunner'
or just
'Beyond Divinity: Riftrunner'

...and personally I never ever did like the name of the first game, so it's hard to add in the word Divinity to a working and decent sounding title.

Still I'm sure the game'll be great...long as I know what it's called when released so I can buy it I dont care!
