A ruin on the floor of Rolara’s oceans. It has not always been there.
Location
The Sunken Temple of Tathra sits beneath the deep waters of Rolara’s seas, in conditions that make ordinary access impractical. The specific depth and approach conditions are not documented.
Its interior has been partially mapped. The flooded halls give onto an astral observatory and, deeper within, a main chamber that was for a long time held dry by a magical air bubble and protected by an ancient ward suppressing intruding magic. A green brazier stands inside that chamber. The ward has since failed and the chamber has flooded.
A cave system lies near enough to the complex that a Large creature can pass between the two, implying at least one opening the surveys have not accounted for.
History
The temple was not always submerged. For most of its existence it stood above water, accessible to those who knew where to find it.
Approximately 250 years before the Reignition of the Stars of Power, dwarves undertook a significant reconstruction of the temple, reinforcing or restoring structures that had decayed or been damaged. This work was substantial enough to leave a distinct dwarven architectural presence within the original structure. The rebuilt temple remained accessible and presumably functional through the late Dark Age.
When Aberran and his expedition successfully reignited the Stars of Power at Three Falls, the resulting upheaval reached the temple. Whether the mechanism was rising water levels, seismic displacement, or a more direct consequence of the magical energies released has not been documented. The temple sank. It has been on the ocean floor since.
The dwarven reconstruction is the most recent above-water phase of the temple’s history. Anyone descending to the site should expect dwarven stonework laid over whatever older construction underlies it.
The Cache
The Temple is believed to have held a cache of Weird Eggs, the progenitor structures from which Bionoids originate. The rumour of such a cache is long-standing and is recorded independently in accounts of the Bionoid exile.
The Solanari Dominion reached the site in 409 TC and held its inner chamber for a period. When the chamber’s ward failed and the ocean broke in, the cache was lost. Whether anything of it survives the flooding is not established.
