What is Crystalsong Forest in World of Warcraft

Crystalsong Forest is the central zone of Northrend, harboring the floating city of Dalaran. Its ground, vegetation and the cretaures that lived there seem to be saturated by magic and have become crystalline. Malygos' blue dragonflight patrols the borders and forests of this place.

It is currently unknown whether it is the direct presence of this Arcane power that drew the Kirin Tor and the blue dragonflight here, or whether their very presence has caused this effect.

There are a couple of questlines that follow in the forest. Mostly people go there for seasonal achievements (i.e. Halloween) or to complete the cooking daily looking for carrots. =) You usually find this forest around level 75 when finding Dalaran.
