Sand Valley is a location from the 1985 animated series She-Ra: Princess of Power.
She-Ra: Princess of Power
Sand Valley was a harsh and desolate place where it was near impossible to grow crops. Despite of this, it houses several inhabited sections, including the 'Low Lands', the Kingdom of Highpoint and Castle Condor.
She-Ra and Swift Wind changed the course of the nearby Green River to channel it towards the Valley. Irrigation trenches enabled the desert land to grow crops, and put an end to the war between Kingdom of Highpoint and Castle Condor.
