Ruins
With the Lord of the Sea by our side, we have prevailed in battle! However, the Deep Devils may yet have the last laugh: they have awakened Leviathan, the evil deity of the depths they worship. If Leviathan attains its full power, there is nothing in the world that can stop it.
No time to regroup or recover, we must head into Leviathan's lair, the city of Ryly'eh, once the seat of Regnos' rule. It is time to defeat the Deep Devils and their malevolent god once and for all!

The Sunken Citadel is the eighteenth stage in Kingdom Rush: Frontiers, and the third and final stage in the Rising Tides mini-campaign.

Trivia

  • The name of the city, Ryly'eh, is a reference to R'lyeh, the nightmare corpse-city that appears in the H. P. Lovecraft short story The Call of Cthulhu, where Cthulhu sleeps, dreaming.
  • On the map, the level flag is placed on a location named Mompoey Island, which is named after Pablo Realini Mompoey, one of the co-founders of Ironhide Game Studio.
  • On the beach near the water-side exit flag, is a half-buried stone hand. This is a reference to a famous scultpure called The Hand by Chilean artist Mario Irarrázabal. It is located in Punta del Este, in Uruguay, which is where Ironhide Game Studio is based.
