The new Noblegarden (which starts tomorrow) has its origins in a druidic festival, but the modern peoples of Azeroth seem more interested in egg-hunting and scoffing chocolates. Focusing on the starter towns like Brill and Goldshire, it's one of those great festivals which is aimed at newer players as well as die-hard level 80s.
Zarhym promises egg hunts and new daily quests as well the chance to find cool items within brightly coloured chocolate eggs. There's also a stack of new achievements (you know you want that Violet Proto-Drake) and if you get sick of eating chocolate you can also use them as currency to buy awesome Noblegarden swag.
WoW Insider will have guides and galleries up tomorrow. Noblegarden runs through next Saturday.
