Guild Wars 2

I was away from this for a couple of years but was prompted to come back by the new expansion. Installed it, but can’t see it in the story tab. Strangely I can see Heart of Thorns, which I haven’t bought. Any ideas?
My only theory is that it’s because I haven’t finished the core game story, which is perhaps integral to the PoF one? Speaking of which, I was slightly miffed to get to the concluding chapter of season 2 only then to be asked to cough up 200 gems to finish it. I think it’s another 400 for season 3. Not sure I’m willing to pay this, having just paid full price for an expansion with no warning that I would need to be up to date with the story to access it. Assuming this is the case.

PoF is not yet released. You will be able to access the story on september 22nd.

Well that makes sense. Thanks.

You are not required to finish previous stories to access PoF. Finishing them helps to understand what is happening but you are able to freely swap between several stories whenever you want. You can play one episode from personal story, then swap to Living World 1 and do one episdoe there, then switch to HoT (if you own it) and finish one episode. It is expected PoF will be same but we can only be completely sure when it gets released.
