One of the most infamous sites in all of Eberron is the prison of Tiamat, the Daughter of Khyber and an overlord of godlike power in her own right. Legend tells that the Pit of Five Sorrows is the single deepest chasm in Khyber that doesn't eventually lead to any other plane. The great dome of force that prevents entry glows with the slowly cycling chromatic hues of the dragonshard below it that imprisons Tiamat's essence. In addition to Tiamat, the pit holds other powerful entities as well as deadly secrets, and it is the most strongly guarded location on Argonnessen. Guarding the pit is a great honor and many dragons volunteer for this duty, even with the knowledge that they will be executed at the completion of their tour to prevent the spread of Taimat's corrupting essence.
