The Dragonkin Lair is a lair found in the Ancient Cavern south of Kuradal. It is initially accessed with the dragon-mithril key. The location is visited during Hero's Welcome and it exists out of a number of rooms where during the quest Dragonkin can be found.
After the completion of Hero's Welcome, players can find three adamant dragons in the dungeon, which drop Sakirth's, Strisath's and Kalibath's journal, as well as Phalaks' experiment log. Adamant dragons in the adamant dragon dungeon also drop these journals.
