How is Dark Messiah connected to Heroes of Might and Magic?

Hmm, it's a bit difficult to say. Since Isabelle gave birth, the child grew up and gained strength... It seems like even the mother should pass away. As for the elves, they might still be around... Although, probably not. It seems like the setting is the Islands (I don't remember the name) where the orcs fled... Probably not. And it seems like you won't be playing as the child, but against him...
In general, there's something about it in the news thread, so take a closer look.
