Dark Deep is an island that appears in many locations in the Franchise, including th TV episode "Quake, Rattle and Roll", as well as several games.
Dark Deep is both the ancestral home of the Gronckles in the Barbaric Archipelago and is one of the only known habitats of the Catastrophic Quaken.
According to Dragons: Rise of Berk, Tide Gliders also live in the area. The Dragon Riders first discovered Dark Deep with the Dragon Eye, when Fishlegs was experimenting with Meatlug's lava.
Geography
In all iterations of Dark Deep, it is a dark, craggy island with little to no vegetation. There are many caves with an extensive network of underground tunnels. In the game, School of Dragons, there is also some pools of lava.
In the app Flight of the Night Fury, Dark Deep has a metallic mineral called "Thor's Ore" that is the best material for Viking shields (this game came out before the advent of Gronckle Iron).
Appearances
Quake, Rattle and Roll
In addition to Gronckles, Dark Deep is also the home to the Catastrophic Quaken –a fearsome Boulder Class dragon that is muscling out the Gronckles for their food source. But the Quaken might have a hidden secret, and the dragon riders must figure it out before the Gronckles are displaced forever.
