Been away for a while ...
You will have missed season 1 as that was temporary content. There is an in game video to catch you up which is actually fairly poor in achieving this.
Season 2 is available for purchase for gold- gems or bought with money. I enjoyed S2 a lot.
Heart of thorns is available to be bought separately or with the upcoming expansion. I enjoyed HoT gameplay, but not the story as much and am excited fir the expac.
Season 3 is available for purchase for gold- gems or bought with money. It had a map per episode and better production values, but was a bit all over the place for story. Some bits were excellent though.
So, you will need to let go some money to catch up, but there is a great deal to play through so you will likely find value in purchase if you enjoy it. I still think it is worth playing should that count for anything.

Thanks for the information Randulf I will look into buying HOT and then this new Fire one as well. This should give me lots to play around with.
Now to look for a Guild once I have found my feet with this game.
