On a more philosophical tangent, the differences between the Vorlons' and the Shadows' beliefs (verbalized as "Who are you?" and "What do you want?", respectively) are nicely illustrated by their choice of anti-planet-scale weaponry.

In comparison, the Shadows deployed a cloud of missles,which is as close to a physical manifestation of chaos as can be used as an effective large-scale weapon.
