Get the quests from Casey, Nosh, and Gerontius. You can wait to get Elle's quest, as
its completion requires items you'll pick up while working for everyone else. Casey
wants better water for the base, which unlocks the filter fountain recipe. Nosh wants
a better cooking crafting station . Gerontius asks for a text called the Farmer Sutra,
which is found inside an ancient palace beyond the red teleportal.
Collect bigonia leaves from the plants found everywhere in the water. You could go
back to your base and build the filter fountain , but there's no pressing need for it.
When you add it to the watering hole, it upgrades to a purification pool. The reward
from Casey is palm lumber (x10).
