Player's Guide to Faerûn
You are one of the generation of dwarf twins born after Moradin's Thunder Blessing in the Year of Thunder.
Region: Dwarf (the Galena Mountains, the Great Rift, the Smoking Mountains, the Spine of the World, the Sword Coast, Turmish, Underdark [Old Shanatar], or Waterdeep).
Benefit: You have a twin brother or sister (fraternal or identical). If your twin is alive and on the same plane, you may attempt a DC 12 Wisdom check to sense his or her direction. If successful, you can note your twin's direction with a move action any time you take the time to do so during the next hour. You can retry this check once per hour.
You also gain a +2 bonus on Diplomacy and Intimidate checks.
Special: You may select this feat only as a 1st-level character. You may have only one regional feat.
