Sword of Truth

From TARDIS Index File, the free Doctor Who reference.

The Sword of Truth was a sacred object to the Peladonians. A double-edged sword, it was the sword used by King Sherak to defend himself from four Aggedors.

The Sword of Truth was kept in a room of artefacts to show visitors to Peladon. It was later stolen by Nic Reece, who intended to sell it. King Tarrol later regained it and used to it to fight against Nic. (NA: Legacy)
