Star of Rassilon
One of the earliest customizations of a TARDIS was done by Rassilon himself. The Star of Rassilon was an exceptionally large green crystal that was installed on Rassilon's Proto-Type 0 Model B TT Capsule. It served as the focus for the dynomorphic projector, vastly boosting the reality quotient stabilizing abilities of the TARDIS. It was this, combined with the Sash of Rassilon, that allowed the Doctor to. One of Rassilon's relatives was using the TARDIS when it materialized inside solid rock on the planet Radirr. The TARDIS was destroyed and the Star of Rassilon was presumed destroyed as well.
Millions of years later, Lord Verostephocalen developed the theory that the Back Time Field Buffers that protect Gallifrey's Relative Past could be penetrated by using the Star of Rassilon, two Type 89 TARDISes working in tandem, and some very complex forced-matter equations. This possibility was to prove too great a temptation for some renegades. The Star was later recovered for a short time by the Master who planned to used it to safely violate the Laws of Time. Fortunately the Master's plan to steal the two Type 89 Capsules was thwarted by the CIA, but the Star remained in the Master's possession.
