Dungeon Explorer 2 Hyvoris Ruins help

[ParanoiaDragon]

I'm at the end of the game, but, I can't for the life of me remember how to get into the rest of the ruins.  Basically, where you find Yuri the Engineer.  There's more to the ruins that I can't access, & I think I've done it in the past, but, I can't remember how.  Anybody?

Also, is there a miniquest for the everbody?  It seems like I didn't have any miniquests for Riot, Gwen, B E, Shun, Miriam, Xan, or Yuri, though, maybe only the main char's have quests?  I did the woods as Dorz quest, I did the cave challenge thing for Alex, I did the hideout thing for Ardin, I did the religious thing for Sorin, I the elf villiage for Fina, & I did the locked door in the desert for Sepi(unless, that isn't his miniquest?).  But, at the least, I can't figure out Riot's.

Yuri has something although I don't know if I'd call it a "quest". You have to meet up with a villager in some town and he will give you a special item. Sorry I can't be more specific than that, I only did it once and it was a while ago.

Where exactly are you trying to go in Hyvoris? I don't recall there being all that much to do there aside from finding the character.

For Yuri, you find his master who gives him a new hammer, which upgrades him.  I figured it out this time around, since, the guy stood out like a sore thumb compared to the other sprites

Anyways, in the very first Hyrvoris area, where you meet Yuri, there's a bunch of blocked off area's that I can't get to, but you can tell they go somewhere, plus there's enemies in those blocked area's.  So, there's gotta be something there.  Also, I might mention, there's one PSG song in the hes file, that, I can't figure out where it takes place, so, since I'm compiling the soundtrack for uploading, I put it last & named "unknown".

Yeah, that's right. The "War Hammer" I think it is.

Maybe I'll load it up tomorrow and see what's doing. I can't remember offhand.

The way I remember it, only the main characters have unique side quests and the "hidden" characters are considered side quests themselves.
