I'm a little confused about the not in the Dragons expansion FAQ saying that Monarch city can become tainted if you place a 4th minion in there. To wit:

"The official answer is yes; adding a 4th Minion (or 3 Demons, or 3 of any minion plus an On Fire Token) will taint Monarch City causing them to lose the game."

I'm a little confused by this since the base game rules say explicitly that Monarch city does not cause taint crystals or overruns. Is there something in the Dragon expansion that says otherwise that I missed?

OVERRUNSs and TAINTED LANDs

Can Monarch City become tainted?

Monarch City cannot become tainted unless 3 Demons were to be located on it since the placing a minion is always allowed. I have never seen 3 demons in Monarch City and think though it may be possible, it is highly unlikely.

House Rule: If, in the unlikely event Monarch City did become tainted by 3 Demons, I would rule that the tarnished city has fallen and the heroes have failed to defend the realm - resulting in an immediate loss.

The decision about the tainting of Monarch City being a game ending condition is one best left to each player group according to the rule they wish to agree upon as a House Rule. It is my opinion that adding the automatic loss condition (especially against the Dragon Generals) may be too harsh for some groups.
So, below is my viewpoint on the options that players can decide upon. I personally use #1, ending the game but see why many may prefer #2 as a House Rule. Those of you seeking an official rule, it would be #1.

1) Anytime Monarch City becomes tainted the game ends and the players failed to defend the realm. This can only occur through Red Minions (3 Demons present or Fire Elementals flaming the location with 3 minions of any type present, but most likely Fire Elementals) as both have the ability to taint without an overrun.

Thematic perspective: This represents the doom of the last stronghold in realm and the destruction of the Royal Council - all hope is lost for mankind.

OR

2) If Monarch City is tainted by Demons or On Fire Conditions, play continues - the game does not end.

Thematic perspective: The Tainting of Monarch City is limited to the land outside of the walls of the city, walls that contain magical gems protecting the inhabitants from the toxic air. The Royal Council continues to direct the war and fight, even though the city is under siege by the Dark Lord's minions.
