Panacea
From Tardis Wiki, the free Doctor Who reference
Panacea was a planet of healing. The Tenth Doctor was trying to take his new companion Majenta Pryce there, to heal her severe amnesia. (COMIC: The Age of Ice, Ghosts of the Northern Line)
Events with the Crimson Hand remedied Majenta's amnesia before they could get there. (COMIC: The Crimson Hand)
