Tegan, Turlough and Nyssa
Only a few days after the events of Enlightenment for the Doctor, Tegan and Turlough, was actually almost half a decade for Nyssa. Meeting again in the Helhiem Gene Tech Centre, the four join together once again, through timey-wimey adventures and returning to Manussa for another battle with the Mara. Together the TARDIS trio and an older and wiser Nyssa have fought Sontarans and Emerald Tigers, until one day, Nyssa's youth was returned and she met Magnus Greel.
