Go to Rabao and talk to Maryoh Comyujah, who's standing in front of the windmill at G-7. She will ask you to do something for her.
Travel to D-12 in Western Altepa Desert and head into Quicksand Caves.
This is the same entrance used for Through the Quicksand Caves.
Head to K-8 and head east through the weight-sensitive door.
The weight sensor takes 1 Galka, 3 Tarutaru, or 2 of any other combination to trigger. Also, any single character with a loadstone can enter.
The door is firmly shut.
Even taru alone can open any door in there while this door wont open with Hume & Taru.Sky access was so close
Edit: Figured it out, thanks to Ciradan. Its bugged and req. 3 ppl no matter of which race you are. (at least it took 2 humes and 1 taru to open it)
