The next day they all went down to the basement of Eureka's house, and was stunned to see it divided in different cubicles. Red, White, Blue and Brown.
"Every cubicle has a circle inscribed on the ground," Eureka started explaining. Pointing at the circles drawn on the floor.
"The colors are pretty obvious, Red is for Fire, White is for Wind and so on. You will squat in the middle of the circle, close your eyes then slowly release your energy. That energy will then activate that circle. But if youe not careful your own ability would consume you."
Raven walked towards the cubicle designated for him.
"And how did you know about such thing?"
"It's not such thing, but a magical circle," Eureka replied.
"A magical circle, then how did you know of it? Our history have no record of it."
"Our history have none. But others have."
"How did you know it will work here then."
