Stargate SG-1/Friendship is magic crossover

Trixie has fled Ponyville and has lost everything, until she accidentally discovers the Stargate. As she examines it, she activates it and decides to step through the pool of light.

SG-1 arrive on P8F-211 to find an azure sentient Unicorn posing as a Goddess after winning over the planet's population with her magic. Is this almighty being for real this time? Or is she another false god?

The team will find out soon enough, especially when a Goa'uld has returned to reclaim the planet!
