God

The gods are supernatural entities residing in another plane in the game. They are usually extremely powerful and quite eccentric to totally insane. The world of mortals would be totally no concern for them if only they didn't have so much abition and desire to have as many and as dedicated followers as possible. Although it is said the gods gather them to fuel their unsatiable ego needs, it is said that some have been known to just toy around with poor mortals. Thus the gods intervene into the lives of 'weak beings' to make them aware of presence of divine force and gain their attention.

It is worthy to carefully think which (if any) god you would like to serve.

Dedicating your lifetime

Some characters start out as believers of certain god. Often they are bound to some god by race and/or alignment choices. Others begin as atheists and have yet to discover a way to sacrifice his lifetime as servant. This might be done by praying at altar, making a suitable donation or worthy sacrifice. Exact way is determined by game.

Staying a follower

Gods usually expect certain behavior from followers. Some may ask to fight the unholy and demonic plagues while others will be pleased by eradicating magic users and yet another bunch will want you to slay all that is pure and good. Your god may like to receive or demand regular sacrifices. You should check what kind of sacrifices these are pleasing because an error will almost surely summon wrath upon you. Various quests and tasks are to be performed in god's name.

The bright side is that as a follower you may be granted special powers which rely on your god's might. You may also be allowed to pray for help to receive divine intervenion. Sometimes a gift may be granted as a sign of appreciation for devotion.

Renouncing religion

At times you may wish to leave your god for another or atheistic life. In many games you will have to change your alignment to switch sides but sometimes a simple declaration (or extremely heretic act) will be sufficient to get excommunicated. Be aware that god may seek revenge.
