The Battledepths annoy me

The Battledepths are driving me mad. If Chromatic Drakes weren't annoying enough, I cannot access level 2. I stumbled upon the dungeon but I dodn't have a quest for it, so do I need a specific quest? I can kill every enemy in there except for one section of the map containing a few groups of Drakes. There is a warp there I cannot reach, and something called the "Heart of", and it's the south eastern corner. I don't have a map part, and can't find one either. Am I missing something here? Any help would be greatly appreciated.

It's Heart of the Shiverpeaks, I don't think it's accessible during the preview weekend. There is also another portal that is currently blocked off by a door which is near the dwarves, this too I believe is unaccessible for this weekend.

Heart of the Shiverpeaks - portal might lead to the mysterious dungeon that seems to be in the Southern Shiverpeaks, in the Frost Gate mission area. Just a guess.

It also seems that the Battledepths isn't fully functional yet, since King Jalis says they will establish their base there and there's no additional quests to follow up.

There are a couple more quests there. Just talk to the dwarfs around there after completing the main quest line, the priest has one and one other (near the exit) gives two masters quest, with some skills and gems as reward, one a diamond and the other quest the new Onyx. There were no exclamation marks above their heads for me, might be a bug/glitch. I just randomly talked to them for fun and found the quests.

But it is either no real Dungeon like the others or it is not functional like one yet.

I got a quest from the guy standing next to King Jalis, had to give him Destroyer Cores, which I unfortunately sold when I visited the merchant just prior to going back into Battledepths to finish working on my Delver title (Deldrimore Title Line).
