No. You can’t use any of that (except perhaps Völuspá if it is the original text or an old translation, not someone else’s modern rewording of it). Full stop. It doesn’t matter if you quote the source, it is still breaking copyright laws. Anything created after about 1920-1929 (I thought it was 1923 but may be 1929 now- you can check if you’re on that borderline) needs to be removed from your game if you plan to publish it.
Edit: What program have you used to get your wordcount? I seemed to hit endings within a couple of choices. Are you sure it’s over 30k words total? That’s important as it will get rejected if it is not (but also needs a rewrite- see comments about the quotes as well). If you just plan to host for free somewhere you can make it as short as you like and might get away with the unauthorised use of other’s works (although you may still get a takedown notice. It’s unlikely they’ll bother to sue you if it’s for free), but HG is commercial so it 100% does matter if that is your plan for the game.
