Davos was a Human native to the Pegasus galaxy. He had one daughter named Linara, and a gift; he could envision events from the future. At one point, he had a vision that Wraith Hive Ships arrive over Vedeena. He warned his people and they all evacuated from their villages into the caves. When the Wraith arrived, everyone hid and no-one was culled. Since then he became the leader of his people.
He envisioned Lt. Colonel John Sheppard's team arriving on his homeworld, in the hopes that he would be cured he was brought back to Atlantis. Unfortunately, he was diagnosed with a lymphatic cancer and there was nothing the Atlantis expedition could do. Before his death he used his gift to show Colonel Samantha Carter the destruction of what she believed to be Atlantis but was in fact the Asuran copy of Atlantis.
