The Sylveste Institute was a prestigious scientific research organisation on Yellowstone, founded and supported by the wealthy Sylveste family, part of the upper crust of Chasm City and of the Yellowstone Demarchy.
As an organisation, the Sylveste Institute conducted research in several scientific fields, including medical technologies, astrobiology and archaeologic research of alien civilizations.
Dan Sylveste was the latest head of the institute. One of his major life projects was organising and leading an expedition of Sylveste Institute researchers and Yellowstone volunteers to the planet Resurgam in the Delta Pavonis system, aboard the Institute-owned lighthugger Lorean. The expedition's goal was to conduct geological research on the planet and archaeological research into its now-vanished alien civilization of avian humanoids, known as the Amarantin.
