Time Sceptre

The Time Sceptre was the core of a TARDIS and where the inside rooms of the ship existed. Like the name suggests, it was in a shape similar to that of a sceptre and existed in another dimension. They were grown using transdimensional engineering techniques and suffused with organic picotechnology elements which gave the TARDIS its sentience and telepathic abilities.
