Step 7: Disposable Villains
In "How to be evil" steps 1 through 3 we've discussed the importance of practicality in playing a bad guy, and in steps 4 through 6 we discussed the advantages and disadvantages of playing a bad guy long term vs. short term. Let's begin today's discussion with the assumption that your at least a little bit sold on the idea of a disposable villain, but you're curious how exactly you could make it work.
One important thing to keep in mind is that you should stay within the limits that a low-level character would possess. Some groups would be fine with you playing a level 6 evil mastermind bent on world domination, but to others it might seem a bit absurd. Maybe if you had a lot of good-looking heirloom armor your disposable villain could wear it could work, but otherwise it's probably better to go with something subtle again -- though not necessarily so subtle that your "villain" isn't really bad to the core. He just shouldn't be the all-powerful son of an old god who lost his memory and hungers for blood. Choose a more local brand of villainy, something that relates more to your friends' characters rather than the grand overarching themes of the entire Warcraft universe.
Step 7a: A Disposable Villain example
Suppose your guild really identifies itself as crusaders against the Scourge, and you decide that your new disposable villain should have some connection to that. You dream up an idea where a small-time troublemaker decides to try and impress the Lich King by secretly infecting some of his enemies with some cursed food that will turn them into zombies.
This could easily be a low-level character you bring into the guild solely for the purpose of this one adventure -- you bring up the roleplay idea with the guild master in private, and you agree to stage a guild interview in which your new villain signs up with the guild as its new cook, offering to make all kinds of food for you. You can level up this character just a little bit if you want, if you want to catch some of your guildmates by surprise, or else you can just park him in the nearest city and have him talk to everyone from there. Either way, once your bad guy has been in the guild for a couple weeks, giving other guild-members some good food to build up their trust, (and "unintentionally" dropping hints of your nefarious plot), you stage a big cook out in a tavern somewhere and get all your friends together, put the diseased grain in someone's meal, "infect" one of them with the curse.
It's a good idea to plan this part out before hand, so that the one you're going to infect is ready to play up the strange sickness he's going to feel afterwards and maybe help give clues that others there are not safe. Some roleplayers don't like it when you just surprise them with a whisper, "Hey! I just infected you with the scourge plague!" So be sure your guild mate wants to play along.
Anyways, once your guild mate starts coughing and gagging on his cursed food, maybe typing out emotes about how his skin is starting to turn pale and splotchy, your character can grow more and more jittery, urging people to eat the food fast, till someone sees what's going on and confronts you. Your character can make a big speech about how pleased the Lich King will be, and how you're not afraid to die because the Lich King will raise you once again, and all that grandiose daydreaming -- but make sure it's just a show, and don't be afraid to let yourself get struck down, put in jail or whatever. You might want to buy or collect some Dark Runes from Scholomance or Demonic Runes from various places ahead of time and keep them handy just in case you want your villain to die at a particular moment. You can mail them to your villain alt and use it just after the rogue in your guild stabs you for dramatic effect.
Anyways, once that story is finished, you'll need a new one, such as finding a cure for the one guild member who ate the cursed food and is now slowly turning into a zombie, for example. You might make another low-level mafia-style crime boss character as the only one who possesses a cure, but wants your friends to pay a hefty price for it in return. Your friends don't dare kill him in cold blood, because he knows where their family members live, so your guild would have to find some other way to convince him or trick him into giving you the cure you need, or maybe find someone he fears more than you to help you out...
Step 8: Social situations work, violence... not so much
Undoubtedly you will think of your own ideas, and in fact, you could have a lot of inspiration if you consider the things your guildmates' characters care about. If your guildmates protect nature, then make a Venture Co. corporate representative who wants to buy up a large part of some forest somewhere, or if they just like to hang out in cities sometimes, then make an annoying reporter for the Gadgetzan Times who's heard of their heroic exploits and always follows them around a lot trying to catch them in embarrassing situations and take pictures with a gnomish picture-snapper device.
Just remember that just because your villain can't beat your friends in a sword fight or blast them with a fireball doesn't mean that he or she can't be scary and nasty in some other way, nor that killing him will necessarily solve the problem. Take it up as a creative challenge to think of 10 different mini-villains your friends might enjoy and ask them which one they like best.
Step 9: Villains in the shadows... (to be continued)
But maybe even after all this, disposable villains aren't your thing? How about a villain you never see, hear or touch, but is nonetheless extremely active in trying to destroy your friends and everything they stand for? Does this sound like Sauron? No, it's you, and you can do it in World of Warcraft.
