In its industrial age, Bastion sits as the smoke-shrouded hub of mankind, surrounded by a world of lurking horrors and cosmic interference. The Underground spreads beneath our feet and the stars loom above. You are an Explorer, braving places too far for maps and too old for records. Your expeditions touch the bizarre, wondrous, and horrific. You search for riches, but also Arcana, mysterious devices with unnatural powers. Mark of the Odd is a rules-light, flavor-heavy roleplaying game of industrial horror and cosmic strangeness. Into the Odd is a simple system that minimizes mechanics in favor of descriptive, fast-paced play. It has been adapted to a variety of genres. The system does not use "roll to hit" mechanics, assuming that everybody hits when they try - combat involves damage rolls, instead. The system does not use perception mechanics, but rewards insightful questions with good information. Chris McDowall is the original creator of Into the Odd, this is the SRD for the Mark of the Odd.
