Where is Dogon's HQ?

Hmmm... this is troubling. It seems like there is a group of people that chose to ignore the danger that lies with the aliens, and instead have begun to SUPPORT them. If this is true, then we're in deep trouble, and I'll really need help from someone like you. Will you help us out one more time?

Thank you so much. Like I previously mentioned, a few alien supporters have built Dogon's HQ at a hidden area around Omega Sector, and have been providing classified information to the aliens. I knew the aliens have been becoming more powerful by day, but this...

The acts like this takes away the liberty and freedom of the innocent people living in this world. We need to find their hidden base and find an item that can be used as an evidence. I'm sure there's a report that's being sent to the aliens by the alien-supporters. I'll be here waiting for you! Good luck!

You must be really busy right now, but this is unlike any other emergency we've experienced, and we really need help from someone like you. If you ever want to change your mind, please talk to me.

Oh... you must have really found Dogon's HQ. I was hoping such would be nothing more than rumors... I guess not. We really have a group of alien-supporters that provide information beneficial to aliens. This is very troubling... anyway, since you found their base, as well as bringing the report here with you, I can't express enough thanks for your hard work. As a reward, here's some money, as well as a pair of earrings.

Thank you so much for your help. All we have to do now is to examine the 4031107 that you brought here. I wonder what's inside... anyway, I'll have to get back to work now, so if you'll excuse me... I'll see you around!
