Well, I've now written 40,000 words of Deathsworn Arc 2 : The Temple of the Mad God. Part 1 was only about 60,000 words in total, but I feel like I've hardly started part 2!
I wanted it to be about 1/3 longer than part 1 - but I think it's genuinely going to need 120,000 words to finish it. At least how it's going at the moment.
