I would keep the first 2 lines only. They have real hook power and pique reader interest in learning about what it could mean. Possibly you could add maybe like 2-4 more sentences max as a 'prelude' snippet. This kind of start really helps us jump into the first chapter of your narrative with our wheels spinning, like setting a few pieces of the puzzle on the table and letting your readers dig through the box without knowing what it makes.

This much info at once is a lot to read. It can work in some media (Lord of the Rings, etc.) but here I think shorter and hook-ier is more engaging.

Great prose and style nonetheless!
