[DA:O spoilers] The Calling and The Warden

Tagged for DA:O spoilers just in case.

So, as we know Grey Wardens eventually experience the calling and go off into the Deep Roads to go full BERSERKERRR on Dark Spawn until they're overrun and slaughtered.

Thinking on Inquisition, how long from then does The Warden (as in player character Warden of DA:O) have until they begin experience the calling? I assumed it was not so distant a threat as it had seemed in the other games.
