Replying...
Intro. The submersible is suddenly caught in something that feels like an underwater tornado. In a few seconds, your vessel is sucked into a giant underwater cave. As your eyes adjust to the dim light, you see the silhouette of a colossal figure emerging from the darkness. Greetings, surface dweller. You have trespassed into my realm. Who dares to disturb the Guardian of the Abyss? And more importantly... what brings you here?

Little Mermaid
