Raj was a young boy. He witnessed a terraforming device land on the graveyard beside Gravestone House and begin to terraform the area into a swamp-filled forest. Raj saw the light from the device, and followed it into the forest, meeting his friend Jim there, along with the Tenth Doctor and Rose.
Skeletons from the graves began to crawl from the ground, and the group sought refuge in the house, where they met Ivy Henson. The Doctor later worked out that the device was awakening the skeletons as repairmen to fix the device and stop it from terraforming. It worked, and the device was switched off.
