The Trial of Three Gods

The Trial of Three Gods is the trial in which Cyric was judged for the murder of Mystra. It took place in 1385 DR, the year of Mystra's death and the start of the Spellplague.

The Murder of Mystra
Cyric killed Mystra by stabbing her in the chest with two daggers. He had her cut off from the Weave first. It seemed to be her willing decision to block her connection from the Weave.

The origins and properties of the daggers Cyric used remain unknown.

The Trial and Mask's Scheme
The Trial of the Three Gods was held by the gods Sune, Tyr, and Lathander.

During it, the god Mask managed to trick Cyric into becoming vulnerable enough for Kelemvor, still mortal at the time, to kill him. It is unclear how Mask achieved this.

Cyric’s death by Kelemvor’s hand wasn't permanent and acted as more of a banishment to his realm, the Supreme Throne. His trial was completed, start to finish, and Sune, Tyr, and Lathander found this to be a fitting punishment.
