As per a few requests, I compiled a few fantasy prompts… but I also realize that these are probably insufficient for your fantasy-related-writing-prompt needs. So, I’d also like to point out fantasyscapes, which has some great potential for inspiring writing. I also think The Art of Animation might be worth your time. That has a great mix of science fiction and fantasy art, although sometimes it’s a bit NSFWish. If you have other good ideas, please let me know. Thanks.
