Spring Crab Day

Table of Contents
The celebration of spring on Ranul.


Prehistoric Times

The oldest evidence of similar festivities can be found in cave paintings dating back to about 142000 NZR. They show the Spring Crab constellation with Kasavoa located inside its body, shining above a dominant figure who appears to be a priest or shaman of some sort. The latter is surrounded by 8 people on either side, oriented towards the center and bowing down with what appear to be offerings in their hands.

Era of the First Civilization

Before the Final War, different nations used to have their own traditional ways of celebrating this occasion. In general, celebrations were more formalized in the territories controlled by the Rilanga Union whereas greater variety was found in those belonging to the Ran-E-Zu Confederation.

Era of Recovery

The idea of celebrating this celestial event played a major role in uniting the survivors of the Final War. It was not only a prime example of their common roots, but also an opportunity for gathering in a comparatively relaxed setting. Furthermore, the beginning of spring was soon associated with the dawn of a new age, which eventually lead to the Spring Crab representing the Rilsu culture in general.


Celebration by the Rilanga

Light played a major role in the Rilanga approach to celebrating this day. Since Mustik Hamesi is facing away from the central star Larekon at that time, families would put up special ornate lanterns to brighten their homes and neighborhoods. Bonfires in communal sites were a common practice as well, and people would often gather to dance around them.

Celebration by the Ran-E-Zu

The Ran-E-Zu focused on the idea of nature waking up and wildlife flourishing. Many animal species on Ranul have their offsprings when the weather gets warmer, which was of special importance to hunters or cattle farmers. The former would gather to build or repair traps and weapons in the days leading up to the celebration. The latter would spend that time grooming and decorating the newly hatched animals. For either group, the presentation of the results formed a central element of the festivities. Most communities used to organize competitions such as voting for the most beautiful animals or marksmanship contests.

Celebration by the Rilsu

True to the idea of blending their ancestral cultures, the Rilsu adopted elements from either side's traditions. In particular, they tend to put up lanterns and strings of light all over their housings, and gather flowers to decorate young animals which are then presented in public parades. People of all ages often gather in brightly lit halls to dance, sing and play music. Many of these gatherings see the guests voting for their favorite performers or play games of skill to win small prizes.


The festivities take place around the time of the year when Kasavoa passes through the Spring Crab constellation. The most opulent celebrations are held on the day when this celestial event occurs, but the precise date depends on Ranul's orbital position.

I love that the festival is based around a constellation! :D I really enjoyed reading about how the different cultures observe the festival, and also the history of it. The idea of all the lanterns the Rilsu put up sounds beautiful. <3

That is a really cool tradition and I like how it is split into three parts like that, and how the evolution of the tradition gives us a lot of insight into the history of the setting! :D   Great stuff <3

The history of the festival brings a lot of insight into the traditions. I also like the part with the lanterns and the reasoning to bring extra light. Wonderful work!

Thank you very much! ^^ I like exploring the history of the different Rul cultures. Everything surrounding the First Civilization and the Final War will be useful for the stories I'm planning to tell eventually. Plus, it's a lot of fun - I kinda feel like an archaeologist uncovering this world's past!
