The Power Of Earth
Arvell stepped through a pair of metallic doors, entering a sizeable sealed-off room.
*SLAM*
After he walked through the doors, they closed with a slam behind him.
From where he was standing, Arvell estimated the room to be 25 m x 25m x 25m cube, with all of the doors, ceilings, walls and floors laden with enchantments to protect against magic attacks.
The floors were also covered in a layer of dirt, some small water puddles, trim shrubbery and other components of nature to simulate outside combat as accurately as possible.
This was just one of the various arenas in the noble's arena, with the entire facility having around 6 similar rooms.
The arena was designed to shelter the entire population of Karsia in case of a future emergency.
Needless to say, there was more than enough space for their purposes.
Above a certain height, the metal wall appeared to have been replaced by a see-through glass-like material, with a set of bleachers on the other side.
