Spectres of the Last War
Humans are still the dominant race on the continent of Khorvaire, though they are not native to it. They can be from most of the Thronehold Treaty nations and will consider the culture of their homeland to be more important than any racial bond with foreigners (e.g. a human from Breland will likely think better of his fellow Brelish citizens, human or not, than another human from Karrnath). Humans worship the Sovereign Host, the Silver Flame, the Blood of Vol, or even the Dark Six or the Dragon Below.
Humans can have Aberrant Marks, the Mark of Finding (House Tharashk—Finders Guild), the Mark of Making (House Cannith—Tinkers Guild, Fabricators Guild), the Mark of Handling (House Vadalis—Handlers Guild), the Mark of Passage (House Orien—Couriers Guild, Transportation Guild), or the Mark of Sentinel (House Deneith—Blademarks Guild, Defenders Guild).
Mechanically, humans gain +2 to one ability score of their choice, making them good at any class they want to choose. They also get a bonus feat, bonus skill, bonus at-will power, and have a racial ability that gives them a +4 bonus on one failed attack or saving throw once per encounter.
