In a single step, Isa had allowed the ice maiden's strength to freeze the very air around her. The gusts of wind that were coming from her ancestor were stopped before reaching her. But the same winds carried flames. Flames from her ancestor that deterred her and all that approached. Only Isa could attempt to take the flames for herself.
The flame sprite had struggled to break through to another level. It had gained a great growth after the taming space but felt that it was unable to truly become strong due to the ice maiden being the main beast used at all times. It lacked the burst of energy it needed to perfectly balance the cold with its flames.
