Dragalvoir is kind but shy, hiding in the deep levels of the ocean among the swaying kelp. It only allows those it trusts to approach its home, and flees while leaving behind a cloud of poison if it feels threatened.
It apparently does not feel the pull of gravity because it supports itself with psychic power. Their poison is strong enough to eat through the hull of a tanker, and they spit it indiscriminately at anything that enters their territory.
