| Auction Commentary & History |
As is the case with the Master series modules, the Companion series had a smaller print run than most of the Basic, Expert, or Immortal series (and had less time to permeate the marketplace before being dropped in favor of the 2nd Edition rules). This slight scarcity is reflected in auction prices.
- CM9 Legacy of Blood: VF: $49 (10/99), NM/SW: $16 (10/99)
