Lucas appeared above the Astral Mystic island just in time for a for a ear bursting roar, along with an earth shaking shockwave to burst out from the water surrounding the island.
A river's worth of water rose into the air along with the shockwaves, and Lucas acted instantly. A terrifying and overbearing yellow burst out from Lucas's being and spread across a vast distance, nullifying the majority of the effects of the shockwaves, and shielding the Astral Mystic island itself, along with the over water city next to it, lest the shockwave flatten and drown them beneath the ocean's waves.
The shockwave wasn't mere shockwave, instead, it was the aura of the ancient horror sleeping beneath the waves of the Astral Mystic island. And at the moment, Lucas could feel his aura struggling against the horror's aura.
"Chancellor!!"
