I admit, I don't really understand this gripe. By the time we get to the banquet, it's possible for us to have met up to 5* of the Seven face to face, and that was them being blatant. What's one more godly face-to-face?<Snip snip>
*Lumia appears at the end of the first dungeon and has her own dedicated quest and NPC hub. Keros appears if you gain entrance to the Kitsune Den and either follow Kiyoko's questline or do favours for other kitsune. Mallach can be encountered in a dream, or if you do certain things after building his temple Hawkthorne. Nareva has a very small appearance during the Convocation of Mirrors quest. And Sorra has an even smaller one in a dream you can have if you're an oviparous harpy. At this point the only God we haven't met (and probably won't) is Velun.
