About the portal to Omega Sector in Nautilus Port...

Which Ariant quest would that be?

Also, another question...

Once you're finished ALL the Ariant quests, is it safe to drop the Picture Badge? It's getting rather annoying sitting in my etc inventory.

It's for Jiyur, he first wants you to get him a pass into the castle, then bribe the guard. It was a really easy quest and didn't have anything to do with area bosses or whatever so I have no idea why we don't have it. It's level 48.

And yeah, I dropped my badge in KMS and still got that quest. But, I dropped it at level 30 so I don't know if I missed quests between level 30 and 48.
