Eh, metagaming is always a hard thing to balance. Too specific and yeah, people read your post and their future actions are influenced by what they know. Too vague and they may later get angry about how you're making things too confusing and vague.

That being said, you can at least act upon OoC of your own character. While [i]I[/i] know everyone else has a different idea for what the dungeon should be, Darc only knows what he wants a Forge. So he told everyone he wants a forge and tries to sell the idea. He's currently annoyed that no one really seems to be offering a counter idea and so far Zaz'ak is the only one who rebukes it, and atm Darc is waiting to hear the rebuttable. And while I know that you initially choose a temple, IC Darc knows that Baganaria is holding her opinion to be a potential tie breaker, which isn't much of a problem for him. He [i]expects[/i] others to have differing opinions which is why he's trying to sell the idea in the first place, even though I myself know that you all choose something I didn't.

Even now he'll still try to vote for the forge until everyone casts a vote verbally, and OoC I'm totally ready to work towards a stronghold if that's what we choose IC. Ya basically just gotta adapt back and forth which is also why I just make Darc matter very blunt and straight forward to just drive the point onwards instead of going around in circles.
