A new WildStar developer diary posted by Carbine Studios talks about the guilds in the game and the benefits that come from being in one.
Carbine wants guilds that are “at once both completely familiar to MMO players, but still brought with it a unique twist.”
The dev diary entry goes in-depth into describing the basics of creating a guild, and describes all of the goodies that come with being in a guild, such as guild holomarks, guild influence, and guild perks.
For instance, guild perks allow guild masters to bestow guild-wide buffs, consumable guild items, and guild unlocks including additional bank vaults and player summoning.
