# Iron

#### 🔥 What is Iron?

Iron is a non-tradable soft-currency produced by your Forges and marks your entry into true late-game development.\
It’s a rare and valuable resource used to build your Castle, unlock deeper tiles, and power the highest-tier upgrades for both Forges and Churches.

Each Forge requires **two Houses** to operate and produce Iron, which makes your town layout planning part of the challenge.\
Production is slow at first, but Iron becomes far more scalable through Church influence, making building synergy the key to reaching end-game efficiency.

#### 🏭 How to Generate Iron

| Source     | Forges (passive production)        |
| ---------- | ---------------------------------- |
| Rate       | Depends on Forge level             |
| Boostable  | ✅ Yes, boosted by Churches         |
| Collection | Passive (auto-generates over time) |

The more advanced your Forge, the more Iron you’ll generate — but upgrading them requires careful balance with Wood and Stone inputs.
