Oathmark: Beginners Guide - Part 1: What is it and how do you play?

About Oathmark: Battles of the Lost Age, from BoardGameGeek:

Oathmark is battle-scale miniatures wargame, featuring 28mm figures drawn up in ranks and files. Each figure is its own playing piece with its own profile: unlike in some systems, they're not just for show, with the unit base as the only mechanically relevant piece. Attacks and other actions are adjudicated by D10 rolls. There is a dedicated miniatures range by North Star. Races include Dwarves, Elves, Goblins, and Humans. -user summary
