Regulus became a Sun Lion Elemental as his energy is more of the sun than fire itself. The angels that were facing him could not take the heat that he is emitting. With a powerful roar, Regulus released a breath of fire that hit the barrier of the floating castle.
"Stop it!" The angels shouted as they knew that the flame breath of Regulus could seriously damage the floating castle.
A light veil suddenly appeared in front of the flame breath as Pristina protected the invisible floating castle. Pristina looked at her subordinates and glared at them because she was supposed to release a spell but she had to protect the castle. She might have buffed them but her subordinates are being reckless.
"Kill that thing." Pristina commanded as she still protected the floating castle as Regulus is not stopping his breath attack.
Edited. Apologies for the delay.
