Celestia famously believes in redemption and rehabilitation. Only the vilest, cruelest offenders find permanent homes in her prisons. Only those lost and damned, and a singular mare kept captive in relative comfort in a high tower of the palace. Her cell is well furnished, and food is brought to her from the royal kitchens from which Celestia herself dines. Among those privileged few in her lady's service, the mare in the high tower is a curious ghost story. What awful crimes must she have committed? What could she do? What but the power to slay gods could keep one small mare in the quadruple sealed apartments they call Death's Vault?
