You really DON'T "need" extra pieces for this adventure...
SPOILERS:
So after all these years I still haven't actually played "the Dark Company" but was recently revisiting it, and looking more closely both at Phoenix's "NA conversion" of it and the scan of the original poster. Looking at it in its original color coded glory I see now what others maybe saw all along but I missed...
For a long time people were asking if they "needed" to buy another HeroQuest game system in order to have "all the pieces" to make this quest "work" properly. Of course we knew that you don't play it with four boards (although that would be "cool" then you would probably need four full sets! and maybe multiple Zargons!). But the board is cleared once all four heroes walk through a "door" to exit the one board and resets it for the next. When you go into the next section the rooms are revealed in the normal way, so sections are blocked off (into 13 color coded sections to be precise). So you are unlikely to run into the "extra" furniture with two exceptions...
In the light blue section there is an actual error. Unless this set came packed with an extra table, there are three tables instead of two. Oops. Just substitute any other piece of furniture that takes up the same basic amount of room (six squares) instead.
The other is if somebody uses "pass through rock" to run into another section, then they could potentially run into other furniture. In theory they could get lucky and even run into the boss (the way to win is to kill the boss monster and his attendants in that section, that is 11 enemies total) and win! Otherwise he may become separated from the party and have to "wait" for them (while the boards reset) and use another door to move about, causing annoyance to Zargon.
There are also two instances where Mentor appears to the Heroes, so if you happen to have the Mythic tier of the remake, here's another opportunity to use him! (otherwise any figure may do or just use your imagination).
So yes, the base game and 12 "mercenaries" for those "dark warriors" and a print out or digital copy of the quest map/notes is all you need to play it.
