I would recommend the TF wiki, my friend! If you can ignore the hate and smarm, it’s a great hub of p much all the information that there is to know about the franchise, story, and characters if you don’t have access to the original material (which none of us English-speakers do!).
I am seriously beginning to wonder if it might be worth it to find somebody to translate the radio drama in its entirety, though. I have all the CDs except one, and the last one is arguably the easiest to get of them all, but I’d need support from what few KP fans there are out there since translation services aren’t cheap.
But that’s long game talk. If you just want pix and info, head over to tfwiki.net!
