This Trait represents a Kindred or group of Kindred who looks out for you, offering guidance or aid once in a while. A mentor may be powerful, but his power need not be direct. Depending on the number of dots in this Background, your mentor might be nothing more than a vampire with a remarkable information network, or might be a centuries-old creature with tremendous influence and supernatural power. He may offer advice, speak to the Prince or Archbishop on your behalf, steer other elders clear of you, or warn you when you are walking into situations you do not understand.
Most often your mentor is your sire, but it could well be any Cainite with an interest in your wellbeing. A high Mentor rating could even represent a group of like-minded vampires, such as the elders of the city's Tremere chantry or a Black Hand cell. Bear in mind that this Trait is not a "Get Out of Jail Free" card. Your mentor will not necessarily arrive like the cavalry whenever you are endangered (and if she does, you are likely to lose a dot or more in this Background after rousing her ire). More, she might occasionally expect something in return for her patronage, which can lead to a number of interesting stories.
A mentor typically remains aloof, giving you useful information or advice out of camaraderie, but will abandon you without a thought if you prove an unworthy or troublesome protégé.
