Zho's Journal

If you fight Zho and her pet Black Moa in The Norn Fighting Tournament (Gunnar's Hold, GW:EN) and successfully beat her, she gives you a journal chronicling her quest to hatch a black moa of her own, and suggests that you can follow the same steps to hatch a black moa for yourself.

This appears to be a new type of quest: it doesn't appear in the quest log, and there are no exclamation marks over NPCs' heads, or arrows or hints in the mini-map. The player must deduce where to go and who to talk to.

Captain Juno in Cavalon (Factions) sends you to Katharine in Gyala Hatchery to obtain an incubator for a Moa egg. Cost: 5 Platinum, 50 Spiritwood Planks and 10 Steel Ingots.

The egg is obtained in Regent Valley outside Fort Ranik (Prophecies). Follow the path directly south from Fort Ranik, fighting the Charr and Renegades that spawn outside. The path soon curves eastward around a bend - here you'll find a number of regular Moa Birds and their nests. Take an egg from one of the nests.

Next stop - back to Echovald Forest.
