But other than that, you have to submit your mare to be approved by the fram who stands the stallion and they must approve your mare in order to go that stallion. Empire Maker wont be hosting any 5 claimers.

I am confused! Does this mean that two of Mr. Prospector's daughters engaged in some equine lesbianism?
