Flying Chariot

If his civilization had access to a durable tree that could be used for building, Alex was sure his world would also resemble this one. 

He observed many individuals moving through the air on devices that appeared to function as hoverboards to Alex's eyes. 

These devices also emitted a transparent barrier shaped like a sphere, protecting the user from the wind and likely from collisions with any foreign objects.

The boards were crafted from wood with a crystal socket in the middle. 

They also varied in size, with the largest Alex saw looking like a floating wooden platform adorned with decorations and a chair on top, similar to a flying chariot.

'How can they sustain themselves with such a population?' Alex wondered.

He then shifted his focus to the surrounding area.
