لغز بالانجليزية..

[Mohamed]

Hello Mourad. The last one was answered, so I let the space to other members to propose a new one.. Well, lets try this one:

Golden treasures I contain, guarded by hundreds and thousands. Stored in a labyrinth where no man walks, yet men come often to seize my gold.
By smoke I am overcome and robbed, then left to build my treasure anew.

What am I?
