Is there a way to convert anything into Emps besides Transcendants

[MsSmart]

Just curious, is there a way to convert something into emps?

[Ukase]

Yes. 5 astrals can be converted into 1 emp at Luna. 

Aside from that, nothing can be made into an empyrean merit, other than breaking down a T-merit. 

Threads can't be amassed to create one, unfortunately.
