Ambassadors from the City State of Binding Light
From Tardis Wiki, the free Doctor Who reference
The Ambassadors of the City State of Binding Light were visitors to the destruction of Earth in the year 5,000,000,000 on Platform One. They were humanoid creatures with pointed ears, multiple eyes and four-fingered hands with claws. They wore long flowing robes. Due to the oxygen sensitivity of their species, the oxygen levels on Platform One are monitored at all times while they are present. (DW: The End of the World)
