Spell Check, Por Favor?
The injury of a God of Life would cause nasty side-effects. Life energy would surge and recede at random, causing booms of birth and growth, de-aging and such- then causing a lack of growth or sluggishness and exhaustion.
But it's the God of
Life. That domain doesn't cause much killing, unless it's because they explode from sheer life-force overload..
But after they have been killed/destroyed- then it more or less stabilizes. The domain would slowly fade.
Life would slowly -but surely- disappear.
If it was, say, Fire, then fire would slowly become harder and harder to make. Eventually, it would be impossible.
Seas would slowly dry up and vanish. Stars would fade away.
They end with a whimper, not a bang.
“She'd become a governess. It was one of the few jobs a known lady could do. And she'd taken to it well. She'd sworn that if she did indeed ever find herself dancing on rooftops with chimney sweeps she'd beat herself to death with her own umbrella.”
