Trust as a resource: how Arventus gates every command.
You never command a person in Arventus — you shape the world a person chooses to act in. Items are diplomacy. Trust gates every request, and every NPC remembers.

Memory: — Mara accepted the +2 Pickaxe gift last week. +4 trust then. Took back the Iron Ingot yesterday — −8 trust, still net positive. Watched a raid kill two apprentices. Mood: guarded.
Arventus is a colony sim × 4X hybrid. You are the mayor of a frontier town and the guild master of an inter-realm adventurer network. The demons are coming. The only question is whether the infrastructure you build will keep the adventurers supplied, repaired, and alive long enough to push back the dark.
And you can't tell anyone to do anything. That's the whole game.
Five trust bands, not three
Every NPC has a trust score from 0 to 100. The score doesn't gate "unlock the next tier" — it gates how they respond to you.
Leave. At this band, an NPC may simply leave town. No fight, no drama — they pack up and walk. Your town has lost a worker.
Asked. You can ask. They can refuse — and your relationship takes a hit when they do. Repeated refusals push trust lower.
Weighed. They'll consider the request. Items they care about, your past record, and their personality all factor in. Refusals don't damage trust, but compliance earns it.
Complies. They'll do what you ask — but the internal model is still active. They're choosing to. They remember everything.
Items are diplomacy
Trust moves with items. Give an NPC a tool that fits their personality or class — +4 trust. Take it back — −8 trust. The asymmetry is on purpose: a gift you can take back isn't a gift. We want you to mean it.
This is the system that makes "shops" and "quests" feel different from every other 4X. You can't just throw money at the problem. You have to know what an NPC values, and you have to keep giving it.
Difficulty escalates with your success
The richer your town gets, the more demons come. A town you built well is a town they hit hardest. The only answer is to expand guild capacity so adventurers can take the fight to the demons — not wait at the wall.
This is the part that makes Arventus a strategy game instead of a city builder. If your NPCs love you, you'll see more raids. If they don't, you'll see fewer — but your town won't have the population to survive them.
Why this matters for design
Every system in Arventus is downstream of this rule: you shape the world, the people choose how to act in it. The guild isn't one building — it's nodes across a kingdom, and each node needs an officer NPC stationed there. If the officer dies, the node withers. If the node withers, the relation bonus decays.
It sounds punishing. It's meant to. The point of the game is to care about the people in it, and the systems punish you when you stop.
Where we are
Arventus is in pre-production with a working prototype of the trust model. We're targeting a Steam Next Fest demo in early 2027. If you want to follow along, the presskit lives at D:\arventus-game\presskit\ and we're posting design notes on the blog here.
