Silver can be found here contemplating his training on Tuesdays and Thursdays. Clair will visit to reward the player with the Rising Badge she refused to award in the Blackthorn Gym, as well as TM24 (DragonBreath)GSC or TM59 (Dragon Pulse)HGSS. This requires fulfilling the task described above. In Pokémon Gold and Silver, where the Dragon Shrine (Japanese: りゅうのほこらDragon Shrine) is closed and everything related to it is unavailable, Clair will instead give the Rising Badge to the player after they collect the Dragon Fang.
In Pokémon HeartGold and SoulSilver, after the player battles Silver at Mt. Moon, they can participate in a Multi Battle with him against Lance and Clair here. Also, in these games, if the player receives the Rising Badge from Clair and then leaves the Dragon's Den with Dig, Teleport, or an Escape Rope, then they must return to her Gym in order to collect the TM.
It is a prize for correctly answering the questions given by the Master in the Dragon Shrine. If any wrong answers are given, the player will still receive a Dratini but it will have Leer instead of ExtremeSpeed.
After completing the quiz, the player will then need to receive TM24 (DragonBreath)C or TM59 (Dragon Pulse)HGSS from Clair. After this, returning to the Master will result in him giving the Dratini to the player.
The Dragon's Den appeared in Fangs For Nothin', where it was reduced to a series of tunnels leading to the Dragon Holy Land. The Dragon Holy Land takes over for the Dragon's Den's other roles, including the location of the Dragon Shrine and the Dragon Fang.
