Tremulously I stand in the subways, absorbed into the terrible reverberations of exploding energy. Fearful, I touch the forest of steel girders loud with the thunder of oncoming trains that shoot past me like projectiles. Inert I stand, riveted in my place. My limbs, paralyzed, refuse to obey the will insistent on haste to board the train while the lightning steed is leashed and its reeling speed checked for a moment.
