Reach Secret Grotto is a large Secret Grotto accessed by a trapdoor located south of Hag Rock Redoubt. It consists of a large cave that breaks into Dwemer ruins. It contains the Orichalcum Cog, as well as a False Majora's Mask and the Dwemer Prototype.
The first room breaks into a large, tunnel-like, flooded cave. Below the surface of the water on the southeast side of the cave lies a doorway to Dwemer ruins. At the end of the underwater passage awaits a hagraven wearing a False Majora's Mask. To the southeast lies a door behind which resides the Goddess of Steam. The Orichalcum Cog and the Dwemer Prototype lay on a stone table on the southeast side of the hallway.
Background and Inspiration Edit
The Reach Secret Grotto was added in Relics of Hyrule version 5.2 and was expanded in version 6.0. Prior to version 6.0, the Dwemer section was not present and the water level in the flooded cave was lower. The wall at the far end of the cave featured small leaks and waterfalls to foreshadow the later expansion.
At the bottom of the flooded section are two parallel beams made of Dwemer metal. These were included in reference to the Spirit Tracks.
