This is a series I read partially something like 15 years ago (I think). It is set in a universe with magic of some sort - I think the magic was derived from geological processes (?). One of the things I remember - which was the reason I abandoned the series - was that it grew ever more gory; when I stopped reading, one of the main protagonists was flayed alive.
I only remember fragments - there were hints that the universe had been magically split into three or four parts, three relatively normal parts and The Void. I remember there was a powerful person/ruler called Tensor, and a kind of monstrous race with powerful magic, called 'Lorsk', which originated in the void and had evolved from humans that had been trapped there.
I'm a bit ambivalent about reading the series again - it seemed to be a never-ending death spiral of soap operatic proportions, but I'd like to see if my impression from then was actually right.
