DAI question

Spoilers through The Thing (as detailed in my previous post). Please no spoilers in comments regarding anything that happens during or after The Thing, except in regards to my question. We haven't finished The Thing yet. Update: Answered, and very quickly! Thanks. :)

( When do sidequests close? )

Vagueish comment on DA:I

I see all these people talking about a certain location in the game and how it's "earlyish" and "the beginning of Act One".

We are finally ready to trigger the quest that will ultimately take us to that location.

We've played for almost 30 hours.

I'm a little bit scared.
