United Lands of the Poseidon Ocean

The connected cities.

The United Lands of the Poseidon Ocean (ポセイドン海の連合国 Poseidon-kai no Rengōkoku) was a kingdom consisting of several islands connected by bridges. It was united by Reginald Kastle, who became the ruler of the land and was well-loved by his people.

The kingdom was eventually attacked by Vector, who led a large fleet of ships in an effort to destroy and loot the land, aided by a group of "Gorgonic Guardians". Reginald ordered the land's soldiers into battle equipped with mirror shields, which were able to defeat the gorgons by reflecting their own weapons back at them. In response, Vector performed a blood sacrifice to call forth the ocean god, Abyss, which turned the tide of the battle to his favor. Reginald's sister Rio rode up to where the ocean god stood and was grabbed by its gargantuan hand. Despite the intervention of Reginald's friend, a knight named Durbe, Rio did not want to be saved and instead pitched herself into the depths to call forth another another god.
