A bit, actually, as they’re very similar to some of the clans of Johto, particularly the Blackthorn Dragon Clan, the (extinct) Alph Clan, and the Houou no Hito (that is, the People of Ho-oh, otherwise known as the subset of Johtonians that consist of sages, kimono girls, and those associated with them specifically), and thus, it’s either fairly easy to understand what Draconid culture is like … or we’ve had historical encounters with them. Either way, you could say it’s a bit of a personal interest of mine.
That having been said, the Draconids had lived in isolation far in the depths of Meteor Falls up until recent times, so consequently, their social and political ties tend to be … sparse, to say the least. That is to say, prior to the event known as the Delta Incident, when their lorekeeper (something akin to a chieftain, of sorts) came into the public and brought the Draconids with her, very few people knew much at all about them. The Blackthorn Dragon Clan knew, of course, but largely, this was because the two groups considered each other rivals, and to this day, the Blackthorns have a bit of a sore spot towards the Draconids. (According to some stories, there might have even been fights between the two over sacred grounds and pokémon, back before the Draconids built the Sky Tower and isolated themselves.) By contrast, while the Houou no Hito are aware of practically every ancient clan a Johtonian culture dealt with at one point or another, the Draconids and the Houou no Hito are largely neutral towards one another, with the latter essentially giving the former liberty to do whatever they want, so long as it doesn’t disrupt Lugia.
Politics aside, as mentioned above, the cultural structures within the Draconid people are similar to the ones you find among the peoples of Johto. Just as with our cultures, the Draconids worship a legendary pokémon (Rayquaza) and place heavy emphasis on the ancient lore of their region (particularly Mega Evolution and the battle between Groudon and Kyogre), which is preserved and retold by a priestess (the lorekeeper). Additionally, the Draconids likewise emphasize the importance of bonding with a pokémon and acknowledging the value of pokémon life (…despite the actions of the current lorekeeper). In fact, said lorekeeper supposedly knows the secrets to summoning the legendary central to their belief system, just as the secret to summoning Ho-oh and Lugia are passed down from kimono girl to kimono girl (or, well, their daughters).
Here’s where the similarities end, of course. As mentioned above, the Draconid people had retreated into an isolated village deep within Meteor Falls ages ago, unlike both the Houou no Hito (which actively embrace the rest of Johto) and the Dragon Clan (which will generally interact with people who venture into Blackthorn City, even if they deny that they ever would). Moreover, the Draconids discouraged visitors by ensuring their village would be difficult to reach, and those that manage would be driven away by high-powered pokémon or assimilated into their clan. All of this, supposedly, was to protect themselves and the secret to summoning Rayquaza, as much of their culture revolved around a prophecy concerning the destruction of the world. This is how the Draconids managed to garner their reputation, and even now, after they’ve opened up their village to visitors and reached out to the outside world, they still carry a certain reputation for being a reserved, somber sort of people.
Admittedly, their customs beyond the retelling of their core stories and the maintenance of their rituals to summon Rayquaza are not particularly understood. It’s always been known that they were responsible for both Sky Pillar and the murals that depict the Weather Triad across Hoenn, but their day-to-day life and customs outside of the Triad have yet to be fully studied. Hopefully, though, things might change, now that the Draconids are open to interacting with the outside world. Perhaps we’ll have ample opportunity to understand them and bridge gaps we’ve never been able to bridge before.
