The Moon

As the prototype suit was ready, he took the first step into the zone ruled by the Moon. It was a slow, intentional stride, fearing being turned into a crushed can with a single movement. 

—Nothing. 

Placing himself on the other side of that gravitational wall, all he felt was a slight pressure against his body, though nothing too intense. 

[Adjusting to gravity vicinity.] 

The monotone, female voice played within his helmet as he could feel the pressure shifting, lessening on his body. 

'It doesn't even feel like I'm standing under anything different now,' he thought. 

To his surprise, the ominous figure in the center of the crater didn't launch an attack against him. It simply stood there, like a pale bark tree in the night, looking his way, though he was unsure if it watched him. 

When it came to engaging with one of the "Major Arcana", he knew it wasn't something to approach lightly.
