Sentinel / Stargate

[ibanara]

Hi there!

I hope someone here can help me ....

I have a story in my head ... and I hope someone here can help me find it again ...

Here is what I think I remember:

- Crossover Sentinel / Stargate
- Blair is a member of the team or at least a temporary member for this one mission
- There is a city on another planet near an old battlefield, where the natives won against the goa'uld
- When SG-1 leaves the planet Blair stays behind to train the native sentinels ...

Anyone any idea?

Please help.

Thanks
