This more or less occurred to me while I was away, some of the Descendant groups have been around for centuries, perhaps millennia in some cases. Therefore, I figured they'd have their own traditions for certain things, such as weddings/engagement. So this is a compilation of these for the main five groups you see in the main Human Order of Guardians series, I will make new chapters for others, such as the Book Guardians and any fan made spirits if anyone wants me too.
I also made this its own chapter because I wasn't sure whether it really fit with the general Descendant Information, although if anyone wants me to write about their spirit OC Descendants, then this information will included in that.
One last thing, minor spoiler ahead for the third arc. Very minor, and you'd have to read the third arc to understand it, and I haven't even started posting that on this website! Yet.
Wedding or Engagement traditions, in order of when the Descendant group joined the Human Order of Guardians.
Descendants of Bunnymund- Present partner or fiancé with a flower, preferably one that they have produced or made from rock. If they do not possess geo or flora kinesis, then a flower is usually grown in advance.
Descendants of Toothiana- A feather is presented to the partner or fiancé, preferably the Descendant's own. This tradition is struggling in the 21st Century as few Descendants of Toothiana possess feathered wings; it is now acceptable to present any brightly coloured feather.
Descendants of Sandman- Partner or fiancé is presented with an item made of tightly packed Dream Sand. What the item is does not matter; although it is preferred that it has personal significance. The item should not disintegrate.
Descendants of North- They did not have the time to come up with such a tradition, as they were accepted into the Order almost as soon as they began to appear. So not to be left out, they came up with one. Their potential partner is to be presented with something small that they built. As with the Descendants of Sandman, almost anything will be acceptable, but preferably the item will have personal significance.
Descendants of Jack Frost-According to what are being referred to as the 'Bergland Books', it is tradition for Descendants of Frost, (at least in the Bergland family) to present their partner or fiancé with a snowflake to wear and it should not melt. This tradition is being accepted by all Descendants of Frost, because it is the only tradition they can draw upon.
Originally some of these were designed for the partner to wear all the time, but in the 21st Century HOG wishes to remain hidden, so they don't have to be worn or kept on the partner's person at all times, like a wedding ring. However it is expected that the items are kept safe for as long as the two are together.
