Wraith Stone

The Wraith Stone is an ancient artifact originally found at the tomb of the Queen of Tiwanaku in Paraíso, Peru. Later discovered by Amanda Evert, she used it to save her life when she was trapped inside the tomb.

The stone could be used to summon the Unknown Entity as well as to obtain some of it's abilities: to create energy blasts and some form of kinetic fields.

The stone was temporarily in the possession of Lara Croft, who took it from Amanda after defeating the creature, locking it in her vault. Amanda eventually got the Wraith Stone back, working with Natla to create a Doppelgänger, to break into Croft Manor and steal it back.

Trivia

 * It is unknown if the Force creature was still able to be summoned after its defeat in Bolivia. The fact that it does not appear in Tomb Raider: Underworld may suggest so, but it's possible the stone could be used to obtain the creature's powers without needing to summon it.
 * In Tomb Raider: Legend the Wraith stone was composed of a black skull-shaped rock with green markings, as seen in the picture. However, in Tomb Raider: Underworld, its composed of a pink diamond like rock headed by black skull markings.
