You'll want to view the ToS at https://www.bungie.net/en/View/Bungie/terms . There's a subsection titled "GAME CONTENT USAGE RULES" that you'll want to read. Also take note that there's additional information on their contact page at https://www.bungie.net/en/pub/contactus from the "What is Bungie’s copyright/trademark policy for the Internet, specifically for fansites? Can I use Bungie and Destiny images, text, video or sound on my web page? Is it ok if I use screenshots I take in-game on my web page?" section and on, so give it a read, too, and also take note of which forms of contact are acceptable. Please note that it's unlikely that you'll get Bungie or Activision's 'prior written permission' so you should assume that anything that requires prior written permission will be beyond what you can do, but you can always try.
