.. Moving Abdullah

There are only two times you can get Abdullah to move. The first is right after you find the burial chamber --

So how do I actually find the burial chamber?

-- and all those people show up.

Where did all these people come from?

One of those people in particular is the kind of person Abdullah dislikes and also in a place where a stranger really should not be. I wonder if Abdullah knows?

After you talk to Jamila, come talk to Abdullah again and ask if he's happy with Jamila being in the tomb. He huffs and puffs, then stomps off to pull his little martinet trip, and his spot is yours for a short time.

Late in the game, sometime after you find and cross the tiles of Destiny --

Finding and Opening the Last Tomb

-- you'll have the opportunity to tell Abdullah about the new sarcophagus you just found. Make sure you've completed all other conversation with him first, however, because this time he may not return at all.
