The speaker is our first boss with a new portrait in several chapters: The only way to get the treasure is to keep the enemy Thieves from getting there in the first place. However in this game, once an enemy Thief loots a treasure chest, it's gone for good - your own Thieves can't steal the item back since there's no stealing in this game, and you won't get the item back by killing the enemy Thief either. If you've only played the later games in the series, you might not see the problem here. The group to the southwest will reach the treasure in just two turns, and we have no one who can get there in time. Being a horrible completionist, I have to get all of them. The other new wrinkle is the set of treasure chests scattered about the map. There are also no forts so no free healing this chapter on the bright side that also means no reinforcements. The pillars are basically indoor trees, providing extra avoidance at the cost of reduced movement. Bow users and mages and the like can still attack through them, but flyers like Sheeda can't fly over them. The new terrain has one major difference though - the walls. There's no real mechanical difference - everyone has the same movement rate, all the mounted units get to ride their horses through the hallways, and we're still asked to seize the objective guarded by a boss.
We've freed Orleans, but there are still some enemies holed up in the castle.
