So last night I saw this post on the blog At the Mountains of Minis:
Chronopia Unliving = Frostgrave zombie.
I knew that mini line name - those horde pygmies minis were Chronopia.
A few random guesses at names later and I found these:
Chronopia 2346: Swamp Goblin Blowpipes
That's them. Hurrah for the internet. I knew it was Chrono-something, deep down, but I couldn't shake "Chronoscope" and that's Reaper's line.
