Unlike with his mission at Astaroth where the moon was very absent and he enjoyed total darkness, this time Kruxe was left with a new moon
Had Kruxe been to the shadow room, he could have simply melded into the darkness and gone invisible irrespective of the little light that the moon was casting on the worlds, but right now, he had to make do with an extreme camouflage and then employ his assassination skill to silently navigate the main deck.
When Kruxe had drawn up his rough plan to get himself on board and deal with Captain Jumo, he had been hit with the question of whether to kill his way to the man or reach him unstained.
The volatility of Kruxe's plan had him risk averse, so without much hesitation, he focused on his primary mission target and forgot about the cannon fodders that were yawning and moving about on the main deck.
