The mentor is a character, usually older or more experienced than other members of the group, who uses his experience to prepare the younger heroes for their ultimate mission or destiny. In addition to acting as an adviser and sometimes teacher, the mentor often acts as the conscience and voice of reason for the group. It is traditional for the mentor to die (or at least retire) once he has taught the younger heroes everything they need to know, but this is not strictly necessary in an RPG setting.
The mentor is one of Campbell's classic archetypes, and appears in some form in most stories, regardless of setting or genre.
The Name Game
Because mentors are usually older than the other characters in the group, they are likely to have "old people" names. They may also have titles to reflect their age and wisdom. Since mentors often hide their true identity from their charges, they may also have a secret (and often famous) name that isn't revealed until late in the game.
Mentors need good Brain Numbers to reflect their wisdom and experience. A high Nerve Number is also typical, since mentors tend to be cool-headed and confident in their abilities. Because mentors are usually old, they are unlikely to have extremely high Body Numbers.

Tools of the Trade
Varies according to the mentor's profession, but most will have a lifetime's worth of trinkets as well as a few very powerful or useful pieces of equipment.
Where You'll Find Him
In all likelihood, the mentor has done his fair share of saving the world and is now ready to take it easy, so you'll probably find him engaging in hobbies like gardening, fishing, or playing the slots.
Because of his advanced age, there's a good chance that most of his old friends are dead or too senile to remember him. While some mentors have families who they keep in touch with, most mentors' only friends are the young heroes who they're training (ie, the other PCs).
