The short answer
The developer describes Horizon as an early safe settlement built by Robyn Cane, where you learn survival systems through tasks, conversations and trade. The Mule visits as a travelling merchant. His launch stock, prices and schedule are not confirmed here.
What Horizon is for
Horizon is described as a place to rest between expeditions, trade for supplies and learn warmth management and crafting. Its isolated hilltop setting is story context, not enough to give you a route from the opening spawn. Follow the current quest information to find it.

Use a visit to resolve one shortage
These are Kingy preparation steps. Avoid building a shopping list around an unverified merchant inventory. If an item is unavailable, keep the shortage explicit and check the documented material leads in the building-tier guide.
- Write down the next blueprint or expedition requirement.
- Compare your missing supplies with the merchant inventory actually shown.
- Check the offered exchange before completing a trade.
- Update your saved plan with what remains missing.

Keep a hub guide separate from a walkthrough
No exact task sequence, merchant restock timer or guaranteed item has been verified. The useful first goal is reaching the settlement and understanding its services, rather than following invented coordinates or dialogue options.
