Trident

The Trident is a magical weapon that grants its wielder great power and the divine right to rule the sea and Atlantica. It's current wielder is King Triton.

Powers & Abilities
The Trident beholds a vast number of magical powers such as the power to command the sea (making tidal waves or whirlpools or even making coluns of water to stand on), control the weather (summoning rain or storms or creating rainbows), unleash blasts of lightning, and even turn living creatures into something else (Ariel into a human and Glut into a small fish). It can also make things disappear.

When not in use, the Trident is kept in the throneroom, on a stand of sorts from which it cannot be removed by anyone but those of royal blood.
