It may not be the most fun world but it is a normal world. Full of normal things. And normal people. Most of your life has been normal. Except that one time when you found that magic artifact and unleashed that magic being. Angel. Demon. Genie. Type thing. Creature. And that's when you got stuck with him. But after such a normal existence it must have been sort of refreshing, right?
You were absolutely stuck with him. Sometimes he'd shadow you. Sometimes he'd shrink in form and perch on your shoulder. He's probably even warmed up to you by now. Maybe. And maybe you to him. He even grants wishes, you see. Three. As most stories go. And it is his solemn duty to protect you no matter what. ...ah..
But his alignment.... what was it?
Lawful Good: He came with a book of rules upon his arrival. One of the biggest ones was that he would not kill innocents. He would not do harm to a lot of people. He wouldn't allow you to use his wishes for anything he personally deemed reprehensible or evil. He's a bit of a stiff, this guy, but his heart is in the right place. There is, of course, the rule of having to obey you, since you are his master. You can force him to do anything you want. But it always seems to pain him. And possibly gets him to resent you more and more each time you try.
Neutral: The list of rules all seemed to have question marks at the end of them.... If you pose anything that's totally on one side of an axis he seems to have to think before granting it or denying it. If you force your domain over him the thinking vanishes and he doesn't really have to think hard on disobeying anymore. You are his master, after all. He doesn't mind you, even when you ask him to do somewhat iffy things.
Chaotic Evil: Kill 'em all. This one is the life of the party. He only questions truly do-goody behavior. But wish for a death on your most hated enemy and he'll surely do it. In front of you. In the most violent manner available to him at the time. Remind him of who's boss and he'll remind you of his magic. But it's of course, the law that he can't kill you, his master. You did read the rule book, right? You should know that...
But what wish stage are you at?
The first: Did you just find said strange magical not normal artifact and are meeting him for the first time? Or maybe we're a little beyond that and you've finally thought of your first wish.
The second: You've gotten somewhat of a handle on him and his abilities (rules, reasons, etc...) and have decided to make your middle wish! Only one more to go. Better use it wisely.
The third: Partings are such sweet sorrow. After this one he's gone. Maybe it makes you glad. Maybe it makes you sad. Perhaps it has taken you years to get to this point because you love him so much and couldn't bear to be parted with him. Ah well. All meetings must have a parting some time...
Of course... you could always wish for a million wishes... Somehow that never seemed to be in the rulebook... And who doesn't want an endless supply of wishes on hand?
((If the extremes don't seem fun enough you can go for the
in-between alignments too just let me know in the comment header.))
