The Last Story (JPN): Gurg's Base / Ruli Castle's Prison:

After a little chit chat with Kanan, you're getting into the Gurg's Military Base. Nothing really hard there going throug many room to find that the Ruli's prisonners are now Gurg's slaves!

Part 30:

Part 31:

There, you got divided, Yuris and Quark got blocked behind some massive rocks, and Elza and Kanan, the other way. You have to do an easy unfinishing fight until Kanan release some sort a Holy Power that finish off the beast! After that you'll get Yuris and Quark back!

Part 32:

You've been "rescued" by the royal guards Trista & Tasha. Flying with somekind of Griffon, you'll try to find the boss of the Gurg's Headquarter. A pretty long fight is starting so (at least 10mn). Hella funny and it'll give lot of exp! When you're done, you can save before entering the boss (and exp a little).

Part 33:

A pretty easy boss pop up then, Margas. You have to stuck him using that green pots on the floor. Nothing really hard (I was lvl 23 before entering there, xped to 27). Once you're done, you'll join Trista's Ship.

Part 34:

You'll have a little talk with all your team regarding Kanan, can you keep her or not. It seems not! After that, you'll bring Kanan back to the King and his son at Ruli's Castle... And they'll jail you. Thanks.

Part 35:

You're in prison with all your team and you find a weird chaps with glasses. It seems you get judged, whiped and thrown back to jail.

Part 36:

As I said, this weird glassed guy, called Lotta will help you to find a way out, you'll then go throug the Underground Secret Path, which seems to lead out. But it's a frozen path full of undeads... Simple and funny since you play back with Seiren & Manamia.

Part 37:

Getting on your way out, crushing ennemies and finding chest using Lotta, until you get the last door...

Part 38:

He's pretty easy, just a spectral caster, that boss summons many ennemis. Just be carefull to not let him cast any spell, and you'll be allright. In the end you'll find a book (a nice treasure eventually) and you'll get back in Ruli's Castle Prison where Trista will talk with you, but won't let you go. Quark seems to be not as friendly as he used to be there...

Part 39:

Back to Ruli's Prison, where the verdict is given, thanks to Trista & Kanan, you are now free again. The Count (Hakushaku) will eventually thanks you for that Gurg's campaign!

Part 40:

After your release, you'll try to find Kanan, at least you've got some word to say to her! 
After that brief meeting, you'll go back to your headquarter, Ariel's Tavern.
