"Abandoned Dwarven" series is my new favourite from Heroic Maps. Great art work. Great "mood" on the maps. And lots of options to put these modular items together. Would be great to have more in this series; maybe more items like stairs; shafts and mechanicals that would link levels in a large deep holdfast. Would also be good to have "Abandon Elven" or "Abandon Orc" series with their own themes.
