[Wasteland scavenging + emotion-driven elements + hard-core mechanical transformation + counter-mainstream technology revival]
Humanity's ruthless exploitation of nature has pushed the world into the abyss of destruction. The steel jungle collapsed, the power grid went out, and civilization was reduced to ashes in greed.
At the darkest moment when all things were silent, mankind unexpectedly discovered a new power that had not been noticed in the past - the power of elements. It is like a treasure buried deep in the earth. The awakened spirit injects the last vitality into the dying world.
With this power, mankind created the glorious "Elemental Age".
Elemental mages became the absolute masters of the new world.
They perceive the heaven and earth, control the elements, regard steam and electricity as "rotten remains of the old era", and denounce mechanical technology as "a taboo that leads to destruction." In this era, wands are better than wrenches and elements are better than blueprints.
However, on the edge of desolation, an expelled "alien" is silently practicing a path that is despised by the world.
