Alea Iacta Est

More a statement of campaign style than of rules, players (especially those of outsider PCs) should be warned that outsiders in my campaigns are subtlely different to those found elsewhere.

Many outsiders are former mortals (not only those that have ascended through a character class; the Book of Exalted Deeds suggests that heaven was empty until the first petitioners arrived, and it is well known that evil petitioners can eventually become fiends), and many more spend a lot of time with them. Even those who are spawned from some concept or alignment become tainted by contact with the flock, since [demi]humanity and its complexities are infectious to someone whose life is so simple.

Because of this, most outsiders (certainly all of those that can be easily met or contacted by mortals) should have at least some human-like qualities, and most will have a full range of mortal foibles. They are just as prone as mortals to like particular things, fall in love, give in to hatred or lust, or any number of other things.

Obviously some outsiders are more likely to succumb to this than others. Most at risk are those who used to be petitioners, and those who were created in a mortal image or in the image of the same entity the mortals were modelled on. Those who have a lot of contact with mortals, especially those who must walk among them in disguise, are particularly prone to becoming like them, as are those that rely on mortal worship (i.e. deities).

On top of this, there is the issue of gender. After being around humans for a while, most outsiders tend to associate themselves with a human gender, considering themselves male or female. Those capable of changing their shape will often take on the physical characteristics of their sex, wearing human-like clothes for modesty (or not, as the case my be). This is especially important to those who masquerade as human. What sex the outsider takes on depends on their personality and personal style, as well as the experiences they have had (one who falls in love with the first mortal they see is likely to make themselves opposite to that person). The exception of course are those that already have some element of gender; mariliths, succubi and erinyes are unlikely to consider themselves male, although it has happened in the past.

Elementals could be affected, but this is unlikely; the elements are inherently more inhuman than the alignments.

You have been warned.
