Here are the alignments you may pick from for your character. Remember, if you are going to be a vermin, you must pick an evil alignment.
Lawful Good Characters of this alignment believe that an orderly, strong society with a moral government can work to make life better to help one another, society as a whole prospers. Therefore, lawful good characters strive for those things that will bring the greatest benefit to the most people and cause the least harm. Lawful good characters keep their word.
Neutral Good These characters believe that a balance of forces is important, but that the concerns of law and chaos do not moderate the need for good. Since the world is vast and contains many beings striving for different goals, a determined pursuit of good will not upset the balance; it may even maintain it.
Chaotic Good Chaotic good characters are strong individualists marked by a streak of kindness and benevolence. They believe in all the virtues of goodness and right, but they have little use for laws and regulations. They have no use for people who "try to push folk around and tell them what to do." Their actions are guided by their own moral compass which, although good, may not always be in perfect agreement with the rest of society.
Lawful Neutral Order and organization are of paramount importance to characters of this alignment. They believe in a strong, well-ordered government, whether that government is a tyranny or benevolent democracy. Laws must be created and obeyed. The benefits of organization and regimentation far outweigh any moral questions raised by their actions. An oath is binding, regardless of consequences. A soldier that never questions his orders would be an example of lawful neutral behavior.
(True) Neutral True neutral characters believe in the ultimate balance of forces, and they refuse to see actions as either good or evil. True neutrals do their best to avoid siding with the forces of either good or evil, law or chaos. It is their duty to see that all of these forces remain in balanced contention. True neutral characters sometimes find themselves forced into rather peculiar alliances. To a great extent, they side with the underdog, sometimes even changing sides as the previous loser becomes the winner.
Chaotic Neutral Chaotic neutral characters believe that there is no order to anything, including their own actions. With this as a guiding principle, they tend to follow whatever whim strikes them at the moment. Good and evil are irrelevant when making a decision. Chaotic neutral characters are extremely difficult to deal with. Such characters have been known to cheerfully and for no apparent purpose gamble away everything they have on the roll of a single die. They are extremely unreliable.
Lawful Evil These characters believe structure and organization elevate those who deserve to rule. They prefer a clearly defined hierarchy between master and servant. If someone is hurt of suffers because of a law that benefits lawful evil characters, too bad. Lawful evil characters obey laws out of fear of punishment or pride of power. Because they honor any contract or oath they have made, lawful evil characters are very careful about giving their word. Once given, they break their word only if they can find a way to do it legally, within the laws of the society.
Neutral Evil Neutral evil characters are primarily concerned with themselves and their own advancement. Their only interest is in getting ahead. If there is a quick and easy way to gain a profit, whether it be legal, questionable, or obviously illegal, they take advantage of it. They are generally quite receptive to bribes.
Chaotic Evil Chaotic evil characters are motivated by the desire for personal gain and pleasure. The strong have the right to take what they want and the weak are there to be exploited. When chaotic evil characters band together, they are not motivated by a desire to cooperate, but rather to oppose powerful enemies. Such a group can be held together only by a strong leader capable of bullying his underlings into obedience. Since leadership is based on raw power, a leader is likely to be replaced at the first sign of weakness by anyone who can take his position away from him by any method.
