Salvage Titan is a black artifact with the ability "Exile three artifact cards from your graveyard: Return Salvage Titan from your graveyard to your hand."
If Salvage Titan is in the graveyard and opponent has Stony Silence in play (which says "activated abilities of artifacts can't be activated"), can I still activate Salvage Titan's ability to return it from graveyard to hand? In other words, does Stony Silence's ability extend to artifacts in the graveyard?
