Project Eden Project Eden was a scientific venture in the Lucifer system with the goal of finding high - mass element s as a possible power source for Earth . The main facility of the project , Belial Base , was situated on the dark side of Lucifer ' s moon Belial . At its heart was the Operations Room , where the neural net was located . The Pit went straight through the centre of the moon , with corridors branching off that the crew made into quarters . On the other side of the Pit , Belial was connected to another moon , Moloch , by a thin but strong fibre called the Bridge . The Lift was a toroidal object that ran between the two bodies along the Bridge . Moloch was a hollow shell filled with vegetation and Moloch Base was located in its interior . Much of the workings of the system were a mystery to the Project Eden crew , not least of all the strange beings who lived on Lucifer called the Angels . ( PROSE : " Lucifer Rising " ) Crew . There were twenty - eight personnel in total . Miles Engado was the Coordinator . The three heads of departments were Christine Lafayette , Chief Psychologist , Piper O ' Rourke , Head of Support Services , and Alex Bannen , Technical Services Supervisor . Federique Moshe - Rabaan was a representative of the Energy Police . These departments frequently clashed over division of energy and resources . Paula Engado , Shmuel Zehavi , and Filo Julee were psychologist s . Craig Richards , Jesus Delporto , Anushkia Smyslov , Satvindha Mudan , Lars Ulrich were scientist s . Julie Ndobe , Chas Varley , Sam Russell , and Tiw Heimdall were technician s and engineer s . Yukio Nakaguchi and Sulio N ' Farr worked on software . Tanetoa was the cook . Also on the crew were Cheryl Russell , Kosiana Kistasami , Rachel McBride , Teal Green , and Brandon Courdry . All of the crew had corneal grafts to be able to see simularities , a holographic medium of video . Supply drones periodically brought news and entertainment . The day was twenty - five hours long , divided into eight hour and forty minute shifts of work , rest , and sleep . ( PROSE : " Lucifer Rising " ) History . The Project began in 2152 . The funding came from Earth Central , substantially due to the intervention of Madrigal Lafayette . One of the crew , Piper O ' Rourke , was a spy for the Interplanetary Mining Corporation . She infected the neural net with a virus that sent information to IMC . In 2157 , the Seventh Doctor , Ace , and Bernice Summerfield arrived on the Project and integrated themselves with the staff . Shortly after their arrival , the Coordinator ' s daughter Paula died , prompting the investigation of an Adjudicator , Bishop . Next , Sam Russell disappeared and Federique Moshe - Rabaan was murdered . Alex Bannen began tinkering with some of the recently discovered machinery in an area within Belial named the Mushroom Farm that had controls operated by emotion . Belial and Moloch started to move out of alignment , killing and injuring some of the crew on the Lift at the time . Earth Central went bankrupt and IMC bought the mining rights to the Lucifer system . IMC sent a fleet led by an multidimensional being known as Legion . Their troopers killed everyone on Moloch except Christine and Ace . IMC set up eight contained black hole s around Lucifer to remove the atmosphere , but the Angels were able to reverse the effect . Bannen once more began to use the Mushroom Farm controls , this time sending out waves of energy that modified morphic field s . Many of the crew had their biologies altered and died gruesome deaths . Only nine of the original crew made it to a shuttle to Earth . The Doctor , Bernice , and Ace were able to put the system to rights using their emotional memories . ( PROSE : " Lucifer Rising " )
