That's right ^.^ the events in the game often based on indonesian culture! Omoed-omoed exists! You can read the details in the mini encyclopedia~ of course, some things are adjusted. *SPOILER ALERT* Like how Mitra showed off his wings--it doesn't apply to the real Omoed-omoed lol.
We also have a lot of version for Batik. Every province has their own Batik patterns so it's a bit complicated but I'm glad to see people are enjoying this tid bits ^///^
