well, I also don't agree that this is some kind of summoning ritual,

but the money definitely goes somewhere :) (let's not speculate on how the money is spent on maintaining the creatures; rather, it's more of a convention that money is spent, as there are no actual costs)

haha, let's also calculate the impact of variable and fixed costs on maintenance... and operating leverage... hee, just kidding

and the fact that angels join for free is reflected in the last mission of the "Long Live the Queen" campaign; they join in droves :)

I think we should consider the game inseparable from the plot.
