asking about our biggest threats is dangerous, unless he chooses to interpret it as "what is the biggest threat to our dungeon heart that is likely to approach us in the next few weeks." Our biggest threat is either a) bigger dungeons (assuming absorbing/ conquering is an option) b) High rank adventurers, or c) beings like the one before us.
I don't want to ask about the lich king. If you want to know about our abilities and potentials ask, what powers do we have the potential to be capable of.
what information do we actually need? Hmm, maybe THAT is a question to ask: Is there any information critical to our existence that we do not already possess?
we need to know:
a) towns, villages, and cities nearby
b) prevalence of adventurers
c) goblin hordes: possible ally?
d) recruitment options
e) our potential relationships with other dungeon
f) information about beings like the one before us. this information is off limits, but we still need that eventually, as he stated that there are others.
Finally, to Adwarf; You are doing great, and I am enjoying this. I do have one tiny little suggestion, though. Work a little on your punctuation and sentence flow. It's not bad at all, but you miss a few commas, and I think you could break up some sentences into smaller sentences for better flow.
