Angle atmosphere (A short lore story)

A small lore filled story in an alternative universe, a one-of-a-kind creature that guards the Earth till up to recently

The funny thing is that I created all of this cool lore because of a science school project that in the group project will create a low carbon emitted island. While reading the instructions, I saw one part saying 'create a legend' without saying anything else; I knew that I must create some cool lore that can be involved with the project lmao.

Not sure if I'm going to expand it even more that just one whole prophecy like speech but if this gets enough support and love, well why not lol.
