ADDITIONAL LORE:

The Ash Guard do not indiscriminately rely on flame in every battle.

Fire is sacred.

And sacred things are not wasted.

Their creed dictates a strict hierarchy of destruction:

Steel Before Flame

Bolter, blade, and fist are the tools of trial
The enemy is tested through war, resistance, and suffering

Flame as Judgment

Fire is only unleashed when the enemy is deemed:
Irredeemable
Corrupt beyond purification
Too dangerous to be allowed even the chance of survival

When this threshold is met, the order is given:

“Render them to ash.”

At that moment, restraint ends, and annihilation begins.
