The Lost Caverns of Tsojcanth feels like a wilderness crawl that ends in a dungeon. Mountains, monsters, a lost mage’s hole full of strange things. Most tables treat the wilderness as travel and the caverns as the prize. That is the dungeon reading. ACKS has another one sitting under it.
The mountains are the campaign.
Whoever holds the pass holds the trade. Whoever maps the hexes decides what the next domain can afford. The caverns are not a random treasure hole. They are the old sanctum of a mage who already understood that power requires a place. Clearing them does not end the story. It gives the party a location others will want, and a reason to decide whether they are explorers or the new owners of the border.
5E runs this as a series of encounters on the way to a boss. ACKS sees an explorer’s endgame. The gold you drag out has to cross the same mountains you just survived. The lowlands market will notice what you bring. The neighboring lords will notice who now sits on the only road that does not freeze solid.
You can loot the caverns and leave.
Or you can treat the module as the moment the map stops being blank. The pass was always a domain. You just had to walk it until someone else had to live with the fact that you knew the way.
