[quote=Athos]
Just to be curious, are the player deaths always caused (directly or indirectly) by the player's actions or are some deaths simply unavoidable?

Bluntly Athos?

Both.

Player actions, direct or otherwise, will definitely have an effect, such as when I had a Goblin of mine jump from an exploding keep with a dead body as his landing platform. He died. Thoroughly.

And then there are the rarer occasions when someone dies simply because the dice picks them out of a pool of victims :p and then puts them back in the pool and holds their head under the surface with a smile.
