The Learning Center was a facility on the Imperial factory world of Metalorn where the children of factory workers would spend time and receive instruction while their parents were on work shifts. Tammia Hollusen frequently escaped the Learning Center to continue her attempts to grow plants in Metalorn's nutrient-deprived soil.
