It is the big building in the north-west of rustboro city.
Its in Rustboro City; a big manor-like building north-west of the PokeCenter.
in emerald you bring it to a guy in Devon corp. in diamond and pearl oreburgh museum
get the fossils go to the Devon corp place an give a guy in there the stones.
Devon Corp. is located in the north-west corner of Rustboro City.
Brawly is the second gym leader. If you have beaten the first gym, and then help the Devon Corp. employee, you will get a letter to send to someone named Steven. The sailor that you helped in the process of helping the Devon Corp will make it up to you by sailing you to Dewford. Brawly's gym is there.
You receive exp share from the president of the Devon corp after delivering the letter to steven, or you can win one from the lottery at lilycove city it is second prize.
Devon Corp. is in Rustburo city, west of the Pokemon gym and North of the house with 2 kids and a mother on the 2nd floor.
