^ looks like the effect will be something like Demon Slayer's Dark Bind skill..

Correct.

So what does that leave for Tempest? We have the two (so far) Nova races, Luminous, and Magnus.

Hyper Skills next? Or maybe some new PQ or something?

There will be a patch this week (Angelic Burster), next week (Magnus) and the week after that which will contain the Hyper Skills ONLY for Nova and Hero classes.
Since we have Grandis World, I think we can expect a lot more maps soon. Now there is only Pantheon and soon Grandis will be expanded with Helisium.
