Back in Susha
Written by MSG Commander
When you get back to Susha, Gaia is busy sublimating the murk, but it's more than he can handle on his own.
Go outside Hugel Temple, and Noelle says Gaia southwest of you (in a village you can only reach by boat).
To reach the village, you actually need to sail east of Hugel Temple, and land on the northern tip of the southeast continent.
(Do NOT try to sail around the island. The enemies in the ocean will kill you!)
When you reach the village, Noelle says Gaia is across the water (on the western continent). However, since you can't sail across the reefs, you'll need to fly there in a Dirigimoo. Izayoi says you might be able to find one in the village.
