The First To Break.

Transcendents can change their shape and size but they can't do so drastically or their existence will fracture. Origins gods can take the transformation further to inanimate objects but it has to conform to their concepts. It is very rare to transform into a 10km being. Such a being also consumes a tonne of Origin energy and deprives others of it.

The ancient battlefield is filled with conflicts. Transcendents from various planes converge there. They are the top dogs in their plane but they become one among many. It led to a lot of conflicts. The numerous cultures and racial differences make cooperating a problem on the ancient battlefield. But that changed when the giants of order arrived at the ancient battlefield. They all gained something that they can agree on unanimously.
