Lu'mian is a very valuable resource with which you can raise an Atlantean pet. Lu'mian comes in three varieties: green, blue, and purple.

Green Lu'mian is required to grow all pets. It can be found:
- During expeditions in the permanent islands
- On the Endless islands
- In a temporary adventure (if any)
