Blizzard's veteran employees receive a Lich King-inspired crown for their service

Polygon: "Blizzard has awarded veteran employees of 20 years with a crown based on art concepts used throughout a number of the company's games, drawing inspiration from the Lich King's helmet from World of Warcraft, Imperius' armor of Diablo 3 and the crown of World of Warcraft's King Terenas, with a hint of curves from Starcraft's Protoss race."
