User summary: This card set was offered to participants in any Mark of Heroes organized play event, but cards were available only in person at certain "kick off" play conventions (Gen Con or Winter Fantasy). Advertised as a "set", the cards were available one at a time. Cards could be "played", as noted on the card itself, to gain some advantage in the organized play program. The Promo set included seven cards from 2004: Heir of Trace or Rune Heir of Life of Dusk Heir of Welcome and Watch Heir of Gust and Path Heir of Beast and Blade Heir of Forge and Sigil Bane of My Enemies
