Something I've realized about this planet...

[Unbound]

Oh, also, I believe "seniority of vibration" is actually referring to "likelihood of being harvestable in this cycle". When this channeling occurred it was not long until harvest began and so they were expressing the way that those who may be able to polarize enough to harvest have a chance to because there is an opening as harvest comes. Entities with more need for development may also choose to come here, but it would be less efficient than going to another third density planet, imo.
