The Lora Trilogy

The Lora Trilogy was a series of Sci-fi prose stories written by Paul Magrs. Although not a Doctor Who spin-off, the series included a number of crossovers with the DWU. The series included the trilogy of novels Lost on Mars, The Martian Girl and The Heart of Mars, as well as the short story The Everlasting Match Girl.

Connections with the DWU
The trilogy heavily features the concept of servo-furnishings, which originate from Magrs' Tenth Doctor novel Sick Building. The Servo characters Toaster and Barbra (who appear throughout the trilogy) also originate from that novel.

Celestial Omnibuses appear across the trilogy as a form of spaceship used in the 19th century.

The Martians of this trilogy share commonalities with the Ninnies who have appeared in the Iris Wildthyme story The Ninnies on Putney Common.

Goomba, a character originating from the Eighth Doctor short story The Wickerwork Man, appears here as a Great Old One slumbering on Mars.

The version of Mars seen in this trilogy may be understood to exist in the DWU as one of the many parallel histories of Mars which are established to coexist in the DWU in the Iris Wildthyme story The Ninnies on Putney Common and later further explored in Iris Wildthyme of Mars and Going Once, Going Twice.
