Reptillian

Reptillians are a mysterious species of sentient beings discovered infiltrating Atlantis by the Kairos crew in the year 999 AB.

When interrogating Reptillian dopplegangers of Clara and an unnamed rogue, the crew was told the Reptillians serve An.

Hashi learned while being interrogated by the doppelgangers that they were aware of the future destruction of Atlantis directly preceeding The Flood.

It was later discovered that the "Alaria" the group had been traveling with was actual a Reptillian doppelganger herself, and could smell other Reptillians.
