This large blue pearl is shot through with criss-crossing brown, green, and gold veins.

These items were originally created by drow and used to command their slaves without stooping to learn their foul languages. The secret of creating pearls of speech long ago became known to bards and others who rely on languages. When you place a pearl of speech upon your tongue (a standard action), it is absorbed into your mouth until you speak the proper command word to release it. While absorbed, the pearl grants you the ability to speak and understand a specific language, such as Dwarven or Draconic. Each pearl is created for a specific language, and you can have only one pearl of speech active at a time.
In addition, while the pearl is active, it can be activated to produce a command effect once per day (Will DC 11 negates).
