Echoes of the Unknown (Fennel Valley)

Strange ruins have appeared in Fennel Valley, a hidden corner of Kanto. Researchers there send you back to Hoenn’s Sage Eron, and the trail leads through a labyrinth full of Unown to a dormant statue of Regidrago.

Before you start

Section titled “Before you start”
  • Finish the first part of Sage Eron’s quest. Play Sage Eron and the Regis up to the point where Eron sends you to his brother in Pacifidlog Town. The Fennel Valley researchers only appear after that.
  • Collect the plates. You need 5 Stone Plates, 5 Icicle Plates and 5 Iron Plates (the Regis drop them) and 5 Splash Plates, 5 Earth Plates and 5 Flame Plates (found by mining).

  6. Return to Fennel Valley. The path to Fennel Valley - Ruins is now open. A group of Unown blocks the way and asks, letter by letter, for the “water gift”: hand over Splash Platex5.

  7. Enter Fennel Cave. Inside, the next Unown wants earth. It floats in the north-east part of the cave. Hand it Earth Platex5 and the way deeper, in the north-west corner, opens.

  9. Wake the Regidrago statue. In the Fennel Ruins stands a statue of Regidrago. It only wakes once you understand “the ancient script”: you must have seen all 28 Unown forms in your Pokédex. Then confirm, and Regidrago breaks free.
