There's this one wallpaper of Cliff proposing to Miranda in the Dragon Islands, which is currently our only glimpse of the place. Can it be featured here? What's the policy on comic-adjacent images such as wallpapers, Q&A comics, etc?
Considering it is based on a canonical event, we could probably use it for the time being until we get more of the islands. If needed, we can use a disclaimer of some kind, or acknowledgement that this is what we know of it so far and might change over time.
For a long time, the only illustration we had of Kieri's parents was the Family Feud wallpaper, which is, uh, dubiously canon at best? So I wasn't sure.
We could also leave the non-Fragaria countries blank for now, since we don't know enough, but that question re:wallpapers is still worth asking in general.
That one is definitely a case by case situation. They could be supplemental in case we need nice quality images of characters, or for group related stuff. There should be a priority for in-comic images for locations if they appear in wallpapers as well. Again, we can always change or remove images as needed.
