 During one attack, Seven of Nine uses an unexploded Krenim chroniton torpedo to devise a method of shielding "Voyager" against the weapons; however, the weapon partially explodes, blinding and severely burning Tuvok.When utilized, the shielding also affects the temporal waves in the region, attracting the attention of the Krenim "time ship", the large vessel that is causing the disruptions.Krenim scientist Annorax (Kurtwood Smith) built the ship to cause "temporal incursions" to be used to erase events from history to strengthen the Krenim Imperium.
