Ghalali Key
From WikiRaider
The Ghalali Key is the second main artifact featured in Tomb Raider: Legend. It is the key of fitting the broken parts of Excalibur together.
It was said to have been a gift to Amelia Croft from her husband and Lara's father, Richard Croft to replace a pendant she lost in Ghana, South Africa. The Ghalali Key was as significant as Excalibur itself, and was sought after by James Rutland and Amanda Evert.
In Tomb Raider: Legend, Lara finds the Ghalali Key at the front of the plane, which crashed in Nepal when she was a young girl, and it is retrieved in the Nepal level of the game.
