3.5 simple guild rules help

[Prax4788]

so i have been running a game and my players keep wanting to interact with the guilds in the world

i remember a book a while back that has rules for guilds and factions including bonuses for achieving levels in the guild.

does anyone what book this is ? or other that have something similar

I think you're thinking of Cityscape. Guilds start on page 84. (Also has similar information on running politics, houses, churches, and other organizations.)

Players handbook II. This has some rules for players creating their own guilds.

[Fax Celestis]

DMG 2 has organization rules and business rules.

CCham has a bunch of sample organizations.
