Inchfad Isle

 was an island in Loch Lomond, Scotland. It was the location of a 162nd century colony during the recolonisation of Earth by the humans of Nerva Beacon.

History
In 16109 or 16110, Roger and Veronica Buchman started began what may have been the first Nerva City colony, and certainly the northernmost, on Inchfad Isle.

However, in 16112, the loch froze over, and the colonists were recalled due to the extreme weather worldwide, and Nerva City was quarantined. When the ice was frozen over, a group of four hundred Wirrn were frozen in the ice.

Years later, Roger Buchman lobbied to restart the Nerva colonies and, by 16127, the Inchfad Isle colony had been restarted.

In 16127, the Sixth Doctor and Flip Jackson arrived on Inchfad by transmat from Nerva City. (AUDIO: Wirrn Isle)
