Shang landed in front of Agon's castle and entered.
As always, the castle was empty except for the throne room.
Shang entered the throne room and saw Agon and Jerald talking about random things.
Agon and Jerald nodded at Shang. "Let's go," Agon said as he walked to his throne.
Instead of sitting down, Agon stopped in front of the throne and summoned his special Communication Crystal.
He extended it towards the back of the throne and held it there for about five seconds.
WHOOOM!
A wave of Mana washed over the throne room as the walls shone in white light for just an instant.
After the white light passed, Shang realized that he couldn't view the things outside the throne room with his Spirit Sense anymore. This was probably some kind of isolation Magic Circle.
SHING!
A couple seconds later, a violet portal appeared beside the steps that led up to Agon's throne.
