It didn't even take more than a couple of minutes for Arnold's forces to mobilise. Even though he didn't have most of his army with him, Arnold knew, he was more than enough to get rid of the planet by himself. But he still wanted to take unforeseen circumstances into the account and decided to let his elite summons accompany him.
In the meantime, he wore his armour and opened up a portal leading to Nilerea's world. Since he had blooded her, he could travel anywhere where she had spent some time. This was the main reason Arnold had decided to blood all of them rather than torture the information out of them.
Once everyone was ready, they all walked into a world none of them had ever been to. Arnold's first concern was whether there would be oxygen on an alien planet or not. That was the reason he wore his armour prior to stepping foot on the alien soil.
