Prehistoric Island

Prehistoric Island is a rare Third Sea sea event, and it is essential for the Draco route. The wiki lists it as the place to obtain the Dragonheart, Dragonstorm, Dino Hood, T-Rex Skull, the Draco race and its Race Awakening, plus the Dragon Egg and, at an extremely rare chance, the Dragon fruit. To spawn it, sail into Sea Danger Level 6 and keep exploring. A Volcanic Magnet is not required, but one player in the exploration group carrying it raises the spawn chance sharply. It spawns day or night, although daytime is easier to navigate, and it despawns only after every player has left. The Fossil Expert appears only here and turns Dinosaur Bones from the Volcano Event into accessories such as the T-Rex Skull and Dino Hood. The event starts when you interact with the Fossil Ancient Relic, the large T-Rex skull in front of the volcano, and you have 5 minutes: keep the volcano pressure down by hitting the orange flames with Destructible Physics moves while protecting the relic from Lava Golems. Anyone not near the island when the relic is touched gets no bones or egg, and the eggs will not spawn if the relic is under 90% health.
