As I sit underneath my bridge I wonder... "Why use their blood which is such a waste of the energy potential? Now those machines in that special effects movie which used people as living batteries - that is an idea! And I bet with the right drugs or even brain surgery you don't even have worry about them dreaming or even waking up."...
All summoned regenerative/non-supply-eating creatures aside I would like to share an observation or two. First, Moral Relativism as a coined term maybe new but the concept goes way back (i.e. Rome's conquering of neighbor nations was good in their viewpoint, but mostly likely not seen as good by anyone else outside the Roman environment).
Second, is anyone else worried that the Nation of Gems might be getting upset about all the sacrifice of their subjects just to cast the spells? I mean the High Diamond must be mustering his gem armies in anticipation to rid the Dominions of this evil happening to his subjects. (Mod pending).

It's just a game right?
