Is it possible Columbina will Enable all Lunar Reactions?

So far. Lunar reactions are sadly locked to 5 stars only until we get confirmation from that leak that Traveller could enable Lunar reactions.

Based on what we've seen, Lunar Reactions are 5 star characters Nodkrai element plus Hydro.

So since Columbina will be a Hydro unit the equivalent of the Archon of the region, it would make sense she grants us access to all Lunar reactions related to Hydro based reactions.
