The Tanoby Ruins (Japanese: アスカナいせきAsukana Ruins) are a part of the explorable area of the seventh of the nine Sevii Islands. The area is essentially useless before completion of the Tanoby Key, but after this puzzle is finished, the Tanoby Chambers become filled with Unown. According to a Ruin Maniac, the Ruins have been around for over 1,500 years for reasons unknown.
The entirety of these ruins is only seven small islets on a calm, blue sea. Within the sea, the standard Water-types are catchable, but within the chambers, only one Pokémon is available in its 28 different variations.
A colored background means that the Pokémon can be found in this location in the specified game. A white background with a colored letter means that the Pokémon cannot be found here.
