Fire and Lightning under the water

After half an hour of constant fighting, the Krakens finally stopped coming out. The dead silence fell and Nemmoxon could only hear the water passing by her closed ears. Gently landing on the sea floor, she looked around for any camouflaged ones.

'Nothing, but just in case.' She used another lightning breath. As the dust was settling down, she became optimistic that no more are coming.

"Let's push ahead, the first wave is done," Nemmoxon told Zaleria as she detected the Aboleth-Kraken cave.

Zaleria slowly swam behind her, she had been holding her breath for half an hour but she still felt fine. Dragon's endurance was extremely high.

The moment they approached the cave, the sea floor split open and sucked Zaleria in. "BLUH!" She gasped and air escaped her lungs. 'Something is mixed with the water…I feel numb…' Zaleria thought as she started drowning. The combination of the high pressure and whatever was in the water was crushing her lungs.
