Treehouse: In a Concrete Jungle

The global cataclysms occurring in the Earthrealm in recent years have left an indelible mark on the very essence of existence. And while some people were trying to fight the evil they had created - others preferred to fly away from the gradually dying planet.
--------------
The remnants of the fruits of a highly developed human civilization, inhabited by crowds of monsters - that's what eventually remained on Earth. Now it was almost impossible to meet a single person who didn't want to devour a curious traveler. Only the occasional stray trade caravan was a reminder that the planet had once been inhabited.
--------------
The destruction of a once high-tech civilization outraged the Aetheric Energy that had been in equilibrium since the creation of time itself. And this outrage was felt in the Mythrealm. The elders of the Twilight Forest community did not know what caused the disturbance of the Aetheric Energy, as the knowledge of the Earthrealm had long been lost, but the more terrible was the unknown of what was happening.
--------------
Yeah... The unknown created fear. Fear constrained movements, fear prevented thinking, fear disturbed the usual life of the inhabitants of the Mythrealm, and it threatened to collapse. The Elders made a difficult decision: one of the creatures of the Twilight Forest had to find out what caused the disturbance of the Aetheric Energy, and for this they would have to acquire a physical shell and find their way to the Earthrealm.
