Chapter One: The Harbor Light
The fog came in off the water just before dawn, swallowing the harbor one mast at a time.

Before you start
Which systems does Proseum run on?
Windows 10 and 11 (64-bit). It installs from the Microsoft Store, so updates arrive automatically.
Do I need an internet connection?
Not for writing or exporting. Proseum only goes online for periodic license checks, and for the AI copilot if you choose to enable it.
What happens when the free trial ends?
Your books stay safe and readable; editing and exporting are locked until you activate a license. Once activated, everything is back exactly as you left it.
Does the AI copilot cost extra?
It’s optional. You use your own key from the provider you pick and pay them directly for what you use — or run a local model for free with Ollama.
Is it suitable for Amazon KDP and print?
Yes. There is a dedicated print-on-demand export with standard trim sizes and bleed, plus a clean EPUB for ebook stores.
Which languages can I write in?
Proseum was built for English from day one and adds complete right-to-left Arabic support. The interface is available in English and Arabic, and you can write books in either, with 50+ Latin and Arabic typefaces.
I got a new computer. Do I lose my license?
No. A license covers one device at a time; contact us and we’ll help you move it to your new PC.
