Not long ago I had the fantastic idea to raise another Guard regiement, In the past, (Cadian) Ive merely followed the fluff and backstory provided. But now I would like to put on my creativity hat and think of my own.

So, Ill get to the point here, Promethium, Flamer fuel.

How Is it made?

What are the chemical components? ie: Is it found naturaly as promethium or do Imperial Engineers need to process/refine it to create our favourite naplam in a can?

Any help by the Warseer think-tanks would be much appreciated. Many thanks in advance
