Two of my favourite shots, showcasing the blue hues that provided bookends for Wrath of the Lich King. The first one shows the Nexus from the outside. Battling the blue dragonflight was a big portion of our introduction to Northrend, particularly those of us who landed on Borean Tundra rather than the Howling Fjorde.
The second picture is from Halls of Reflection, as we come upon Frostmourne. The spirits circle around the famed sword. It was a matter of time before we fought its wielder or became a part of it.
