The Sea Gate

The Sea Gate is the fifth episode of She-Ra and the Princesses of Power. It was released on Netflix with the rest of the first season on November 13, 2018.

Synopsis
''The squad heads for the water realm of Salineas, ruled by Princess Mermista, but first they need a ship. Catra sets sail with Force captain Scorpia.''

Plot
Adora, Glimmer and Bow head to Salineas to convince Princess Mermista to join the Princess Alliance. Needing a ship, they charter the services of Captain Sea Hawk who claims to know Mermista personally. Meanwhile, Shadow Weaver sends Force Captains Catra and Scorpia with a crew to attack the Salineas Sea Gate. With the Sea Gate failing, She-Ra uses the Sword of Protection to repair the mystical barrier while her friend and new allies defeat the Horde forces.
