A planet whose Parallax Colony of artists and free spirits was recreated on the Enterprise-D holodeck by Lwaxana Troi to entertain Alexander Rozhenko.
Shiralea VI is a planet whose Parallax Colony appears as a holodeck programme in the Next Generation episode Cost of Living.
Lwaxana Troi, aboard to marry a stiff official from Kostolain whom she has never met, befriends Worf's son Alexander. She takes him to the holodeck to see the colony, a place of jugglers, dancers, a fire sculptor and quarrelling philosophers, where the main rule is to enjoy oneself.
The two skip Alexander's appointments to soak in its mud baths. The visits remind Lwaxana of what she would be giving up, and she arrives at her wedding in the Betazoid fashion, unclothed, which sends the groom and his protocol minister away.
