Government House
From Tardis Wiki, the free Doctor Who reference
Government House was the seat of government on Trion under the Revolutionary Regime. It was where Vislor Turlough's inquisition that led to his exile to Earth was held.
The House was a modest five-storey building with a polished silver exterior that reflected back all light. It was often impossible to see the entrance due to the reflections unless one already knew where it was. There were no steps up the entrance. In one timeline, it was home to President Commissioner Naale Niairb. (PROSE: Turlough and the Earthlink Dilemma)
