The Osirans, also called Osirians, were a race of powerful and intelligent humanoids of god-like power in Doctor Who. They were worshipped by many cultures across the universe, including on Earth in ancient Egypt. They were ancient, having been a major power since at least 150 million BC.
They were said to be almost as powerful as the Time Lords. They had a wide variety of advanced psychic powers, including mental and physical projection, mind control and telepathy. They could live for thousands of years and thus did not have to concern themselves with death, children, or the future, and so customarily married brother to sister.
Osiran technology was based on the mathematics of topology, positioning and shapes. They would be specially aligned to the stars in order to work. For example, the Osirans set up the Pyramids on Mars and Earth as power receivers.
They used Lodestones which were a type of time travel technology, generally embedded into a sarcophagus. These lodestones created a time tunnel, allowing the Osirans to travel backwards and forwards in time. These lodestones could draw in vortex energy, which could pull in a TARDIS.
