Will there be secret crypts hidden in the game world, rooms where the players themselves will discover them by accident? these places will not be marked in any way on minimap or by quest - such an Easter egg?
and in these places we can find items, npc, mobs, books with some history?

yes. Rogues will have a utility skill which locates hidden doors/room etc.
