Follow the guidance provided by @BetweenMyself. Furthermore, it's always best to get permission... I'd say generally you'll be okay. Byf monetizes... Destinypedia monetizes. Here's what they might not be cool with, using Bungie merchandise to promote your content without permission. I mean as a prize. Because no one does that... I think Myelin got permission to give a few away before he told the entire community to **** off. TLDR, follow the guidelines in the link. Finally, a warning... IF you wade into lore, be ready... for Byf scholars & for the most obsessive contingent of the community to come after you. Make sure your mods are on point.
