Thetis

Thetis was one of the Nereids from Greek mythology.

Abode
Thetis was the leader of the Nereids and the goddess of the sea.

Achilles
Thetis was a beautiful nymph and many gods, including Zeus and Poseidon, wanted to marry her. However, Themis prophecied that Thetis would bear her husband a son who would grow up to be greater than his father. This caused all of her godly suitors to lose interest in her. Zeus then wed her to Peleus and she gave birth to Achilles.

In order to protect her son, she bathed him in the River Styx which made him invulnerable except in his heel.
