Fairly minor and innocuous suggestion, but it would do some for flavor. Some time ago, people were asking for I think the Lasallian Lyre to be offered as bagpipes, and it was offered, on auction. I believe @Kyrra
won it? I am not totally sure on that.
There are many items in mythology that can be equated with the Ring of Flying or the various Wings. Icarus's shoes from Greek mythology, the flying carpet from Middle Eastern stories and the flying broom. The function doesn't have to be different, but it would be pretty cool to see a person flying with glowing winged shoes or sitting on a broom. The function would be the same as Ring of Flying. Alternatively, the item might be offered as a two-in-one of Ring of Flying and Eagle Wings.
An innovation on the whole scheme could be a room of teleportation within someone's home, sold as a Housing upgrade for room credits like no-prism rooms. Add the housing upgrade to a room, say a magic word (different from Duanathar,) and you're taken to Clouds. I don't imagine it'll ever become ultra popular, because wings can be used anywhere outside, while this can only be used in one room in one place. The one boon is it's an indoor thing. But, it would be an interesting upgrade, if implemented.
Thank you for reading my idea.
