Ot's Armband of Faithfulness (By Steve Miller)
Three of these delicate gold armband are known to exist, each engraved with the symbol of Ott, They were created by Mongolian shamans during the years 800-1300. C.E. Ott is the Mongolian goddess of marriage and fire, and these items are reported to make the bond of marriage unbreakable between a husband and wife. Once one spouse makes a gift of an armband of faithfulnesss, neither of them can betray the other without dire consequences.
   One of these items was originally been owned by Borte, the wife and true love Temujin, the Mongol emperor known as Genghis Khan. Legend holds that she insisted it be used to bond her and Temujin together after she was abducted and raped by members of the Merkit tribe, because she wanted to know her husband would never doubt her love and faithfulness to him. Although Temujin never doubted her, he acquiessed to her demand.

Once an armband of faithfulness is exchanged between duly married partners, the giver and receiver are both subject to a powerful curse that can only be lifted by the goddess Ot herself. The curse manifests itself in two different ways:
   The recipient feels a compulsion to wear the armband at all times and could be said to feel naked without it. If the character should ever attempt to betray his or her spouse, all skill checks or saving throws involved are subject to a -4 penalty. When the betrayal is complete, any characters actively taking part in the action must roll a successful Will save (DC23) or be filled with a homicidal rage that only subsides when the recipient is dead. If the save is successful. the characters are filled with disgust and loathing for the recipient.
   The giver suffers no ill effects until he or she commits an act of betrayal against the Recipient. The moment the act is complete, the character immediately bursts into fire that cannot be extinguished, suffering 6d6 points of damage. The character continues to burn for three more rounds, suffering 4d6 points of damage, 2d6 points of damage, and finally 1d6 points of damage. If the character drops below 0 hit points, his or her body dissolves into a fine ash from which no resurrection is possible. If the character lives, he or she is horribly disfigured and crippled, immediately suffering a 10-point reduction to Strength, Dex, and Charisma attribute scores (to a minimum of 1).
