I’ve been eagerly awaiting the following time these two brothers meet once more. Now that Kelius has a Starcaster, he received’t present his brother the identical deference.
And for all that he’s a genocidal monster, Vectanix does what he does as a result of he genuinely believes that he’s serving some larger good. I don’t assume he sees violence and energy as inherently good, however merely essential evils. Kelius appears to be the other: he revels within the violence and energy itself, and see the “trigger” as merely a car to fulfill his bloodlust.
I foresee Vectanix killing their father, ultimately.
