P6S-221

P6S-221 was a planet in the Pegasus galaxy which held a Stargate as well as a local population. The locals thought that if they wore hats it would keep the Wraith away and so, when Atlantis 1 visited the planet sometime before they discovered a giant Quantum Mirror, Teyla Emmagan was happy to humor the people and wear a hat, along with the rest of the team.
