Not as such. The Illuminants are more on the Arcana's level than ours, in the sense that they're powerful beings bound to the archetypes they represent. They're not nearly as understanding of needs outside their own, though, and... well, the Arcana don't always have a firm grasp on that. [Some of them try, though, and that's more than Naoki can say for the Illuminants.]

They took exception to the Arcana coming and meddling with their sandbox, so they broke into Liminal Space near the end of the dragon mess and tried to bring the fight to the Arcana. If you want to know more about that, ask Maria-chan - she seems to be the most willing of the involved Travelers to talk about it.
