NPC Construction Guide

In large part, this is precisely as presented by White Wolf in Children of the Night page 5 and the Storytellers Handbook page 53 with a bit of better definition on a few different facets:
 * Determine active years of the NPC (current year - year Embraced - time in torpor).
 * Attributes: apply the basic 7/5/3 spread. Add 2 more dots to all Attributes for each century active, up to 500 years, and 1 more dot for each century beyond 500 years.
 * Abilities: apply the basic 13/9/5 spread. Add 5 more dots for each century active.
 * Disciplines: apply a number of dots equal to the square root of years active. For Necromancy/Thaumaturgy, apply a number of Rituals per each dot, equal to the level of the Path dot.
 * Virtues: apply the usual 7 dots. Remember that Conviction and Instinct do not receive a free dot.
 * Morality Path: Determined normally - a number of dots based on years active; 200 years or less = 1, 200-350 = 2, 350-500 = 3, 500-750 = 4, 750+ = 5.
 * Willpower: Determined normally + a number of dots based on years active, as above. May sacrifice Willpower dots to increase Morality Path.
 * Backgrounds: determine Clan Prestige, Generation and Status as appropriate to the NPC's role, then apply the basic 5 dots then add 3 for each century of years active. Sabbat NPC's do not start with 5 dots and only add 2 for each century of years active. Lastly, add a number of extra dots equal to the character Humanity rating (if they possess it).
