I said there were four short stories total that link directly into SEVEN FORGES and I meant it. Each of them expands upon aspects of the novel. Each of them is designed to add to the experience but none of them are meant to be essential. Think of them as deleted scenes cut for the sole purpose of making the movie fit into the allotted time frame if you like, even though they were written after the fact.
In any event, here's the link to the last of them: WHEN KORWA FELL. I truly hope you enjoy it.
