Vault of Stellar Curios

The Vault of Stellar Curios was a Jariden facility where Kalinda Ulrik worked. It was visited by the Fifth Doctor and the Eighth Doctor at the same time, both attracted by a leak of chronon particles. It was attacked by the Daleks, led by the Dalek Prime, their aim being the contents of its inner vault, a weapon known as the Jariden device. (AUDIO: The Four Doctors)
