It's simple enough. I am a Heroic Spirit, a servant summoned from the past to fight the battles of mortals. The contract works as follows. Your position would be to provide power and usually strategy . . . in return, you will be able to alter my path no less than three times. [holds up three fingers] Three absolute commands where your will can supersede my own.

Other Heroic Spirits tend to be more obedient to their masters at other times, but . . . [chuckle] my class doesn't tend toward that. How dull. But a contract is a contract. We could try to work together.
