The 'voice of doom' potion was an item that was involved in the 2007 Halloween event, during which the player completed a series of chores meant for the Grim Reaper's late assistant. It was found by searching the fireplace, and it needed to be placed on the bookshelf. The potion in question could not be used by players. This item is now discontinued and no longer exists in RuneScape.
