Dragon Guardians of Tomorrow

The Dragon Guardians of Tomorrow are dragons of the upper atmosphere which have been cursed to be bound to the sands of the Island of Tomorrow for 100 years or until a worthy king is found.

They prevent anyone from landing on Tomorrow by taking them up to "Death by Aerial Oblivion". This punishment was given to Ug the Uglithug who attempted to land on Tomorrow with fake things, and to Alvin who broke the laws of single combat. Hiccup was dropped by the Guardian Dragons, as he still had one lost thing, and the Dragons recognised his claim for kingship need to be answered.

Dragons, even huge sea dragons and Woden's nightmares refuse to come onto the beach of Tomorrow, for fear of the Guardian Dragons.

After being given their freedom by Hiccup, the Guardian Dragons return to the upper atmosphere, where they can be seen as "shooting stars".
