Can I move Personality with Iron Armor attached using action granted by Accessiable Terrain?
My first thought was no, as Iron Armor ignores card effects, but after reading them carefully I am not so sure anymore. Accessiable Terrain is only source of player ability to move into armies and player abilities are not restricted by Iron Armor's trait. So technically question is: Is player ability granted by a card (e.g. Combat at Court, Accessiable Terrain, Severed from the Emperor) considered to be a card effect?
Card effects will not move this Personality. Melee and Ranged Attacks targeting this Personality have -2 strength.
The Attacker and Defender each have the ability, "Absent Repeatable Battle: Move your target Personality at any location to this battlefield." Absent Battle: Destroy a Terrain (if able). Put this Terrain into play.

Since the ability is granted by Accessible Terrain, it is a card effect, and Iron Armor will stop it.
