So we all know the big finish and what happens, yadda yadda.

Do you think Black Library will actually put it in a book? Of course they will would be a natural answer. But really, how do you about writing a battle between beings that are so colossal, possibly beyond our scope of comprehension?

This isn't Yoda versus Darth Sidious, it's the Emperor of Mankind versus his greatest son, jacked up on Chaos. I think Horus vs Sanguinius is a writable showdown. But Horus vs the Emperor is probably that times 1000.

Do you think it can be done justice?
