You gain a third for the first time when you unlock the EMA bonus quest series - but it will only be occupied by those bonus quests and go away once you're completed. Shortly into bronze age you pick up a second. When you first start the game you just have one. The game has up to 3 quest slots in the "Story" tab at any given point in time.

Intertwined with the great building is the game's recurring quest system, so I should take some time to explain that first. When should you build it? How high should you take it? "It's complicated". Pretty much every top player has one, but it's relied on to different extents. This building is one of the great "not-so-secrets" of longtime players.
