The Bronze Mirrors

The Bronze Mirrors, as seen by Spec-tacular in his first vision are what is used to create the Blooms.

To use them requires mastery of one of The Glyphs .

They are very old.

In look they are all in one room and are concave bronze affairs.

They are in the Quantum Tree, although it is likely there is one in our world.

More modern devices where discovered in the October Revolution Island Bloom
