Can't complain about the 5 easy badges.

Sort of uninspiring, but a good step-up to instancing in Northrend.

While the gameplay leaves much to be desired, I love the art direction both in terms of visuals and audio in this instance.

Originally the exclusive domain of Malygos, the Aspect of the blue dragonflight, the Nexus has expanded considerably as other blue dragons choose to live near their leader and partake of his wisdom. The Nexus is an extensive series of caves and tunnels that riddles Coldarra. Every space has been carved and smoothed so that it seems more like a castle buried in ice than a natural formation. The walls are ice and crystal, and cast rainbows of light from small glowing gems set in strategic locations; most flat surfaces are carved to show dragons in various activities. The floors are solid stone, polished glass-smooth and mirror-bright. No stairs exist - in many places an archway opens onto a vast open chamber and the dragons simply fly across to another portal placed somewhere on the other side. The outermost chambers are dotted with lifelike ice statues - the statues are the remains of uninvited guests, transformed by dragon magic and placed here as a warning. The caves themselves are fascinating, and many have unusual magical properties, some of the rooms may actually change.
