Literature

Scrolls are the literature of Pyrrhia, written and read by most of the dragon tribes. They are printed with ink on some sort of paper.

Tribes

MudWings - In The Dark Secret, Sora said she was reading about the prophecy, hinting that MudWings read scrolls.

SandWings - Thorn of the Outclaws has been shown writing "Wanted" posters, and these are likely scrolls. Also, Smolder intercepts messages written on scrolls, and it can be assumed that most SandWings read scrolls.

SkyWings - Peril lied to Scarlet about reading about the Champion's Shield in a scroll, and Queen Scarlet replied, saying "With claws that burn through paper right when you touch it.", which reveals that SkyWings read scrolls. They also use scrolls for messaging.

SeaWings - The SeaWings read scrolls, most of them written by Queen Coral. Some of her work includes The Missing Princess, The Tragedy of Orca, The Claws of Murder, A Tail of Blood, and many other stories, all of which are taught in SeaWing schools. The scrolls are written with a mixture of whale blood and squid ink, created by Whirlpool, to make them waterproof.

RainWings - RainWings didn't read scrolls and never knew about them or the rest of Pyrrhia until Glory claimed the throne.

IceWings - It is unknown if IceWings read scrolls.

NightWings - The NightWings read scrolls and wrote several of them, and Starflight and Mastermind have always been fascinated by them. There used to be a large library at the Night Kingdom.
