using the truth as a lie, how clever..

the gemstone is now bright. essentially you're doing the opposite of Side A, unknowingly going along with weakening the seals...

then the same portion of Thanatos Tower as shown in Side A...

Your character must first receive a Letter of Recommendation from their respective NPC, then head to the Morroc Bar (possibly Assassin Bar).

You then go into an area where you have a limited amount of time to talk to the NPCs and are presented with a choice of which mission you wish to take. You may either go with Kidd:

or with Lin: 

The dialogue for Assassins varies slightly from the other classes.

Side A goes with Kidd.

Head to Juno...

If you didn't notice, the crest is now dull, whereas before it was shiny.

Yes, because a cute hat will hide my Assassin outfit.

Kidd's dialogue there is possibly my favorite in this entire quest.

And then comes my least favorite part of the quest... literally the reason I hated doing it. You have to go TO THANATOS TOWER...

climb up to the FOURTH FLOOR... to find this MACHINE...

and have to do basically a NUMBER GUESSING GAME. I think if you're good at math and/or puzzles it's easier, but for me it SUCKED.

Obviously, if you get the number wrong, you have to start again. But eventually...

Then within the Morroc Castle...

You walk along this rainbow road for a while but it is super creepy... at certain intervals you get these popups and regularly dialogue appears at the top of the screen...

BTW, with every one of these dialogues, you get the Blind status.

Also, weirdly enough, the dialogues reference the Ragnarok manhwa. There actually IS a man in Morroc Castle who is taking children and killing them (in the scene we see, he is lowering them into a boiling pot, hence the smoke), and every time it IS a full moon and the guards are increased.

The road goes on for a long time but finally you reach the end...
