Spoiler: Adventure Y

SamuelVarg

If I understand correctly The Black Pits is Adventure X. Awesome!

But what is Adventure Y? The new characters side quests? Don't get it...

I have an advertisement for Adventure Y:

"Adventure Y - when you see it, you will shit bricks"

Cool, I hadn't heard about this! I'll wait patiently. For a time *shifty eyes*

My guess is that Adventure Y is a bridge between BG and BG2.

But! - Hopefully is an adventure that reveals that "Throne of Bhaal" was all a bad dream.

Here's my guesses from reading threads referenced by @Anton and @mch202 and some drunk tweets (lol):

Adventure Y is Dorn's sidequest into a mountainous area wherein there is a snappy Arabicish soundtrack. This adventure has bhaalspawn implications. The end.

Adventure X is a side adventure, while Adventure Y is an optional storyline piece in the Bhallspawn series

" What plans, if any, do you have to add any content to the game for this new edition in terms of new adventures, characters and gameplay?
We have plans within plans in this area. So far we have announced one new potential party member. He comes with a class which is new to Baldur's Gate and a story-based adventure which integrates into the existing Baldur's Gate story. We've also announced a new adventure which exists outside the Bhaalspawn story and should be a lot of fun to play."
- new adventure X which exists outside the Bhaalspawn story= black pits
- new party member with new class is Dorn, the "story-based adventure which integrates into the existing Baldur's Gate story" must be adventure Y

From wikipedia, Adventure Y was meant to alter the bhaalspawn story by expanding it....I was wondering, actually, if adventure Y was related to Dorn il-Khan. Please note that, of all new NPCs, he is the only one without any zone added. So he's just a new NPC with a side quest, a kit, and a few monsters in current areas? Somehow I find this a bit fishy. Especially considering he is named after Grommir il-Khan (a bhaalspawn).

Where?

Concept art also showed Dragonspear Castle, just north of Baldur's Gate. Haven't heard anything about it though. Could be going in that direction.

Final word:
