Sil the Great
The Blade ship was large and over the course of a 1000 years, there were now 1000 of those that had the Blade ability as it was passed down to their family members and more. On top of that, the Blade community had become more than just those from the Blades, it had more so become a faction.
Honestly, during the 1000 years, just like in the past due to their strong ability, the Blades were feared and felt like they were unmatched in terms of power. They hadn't directly got involved with the ongoing dispute between the Pure faction and the Green's but that was mainly because Logan had told them not to, due to the nature of the humans during that time.
Which was why, even though it was the first time the Blades had ever had an intruder be able to come aboard their ship, no one was scared and was ready to take them on. However, possibly the strongest Blade in existence was frightened.
