Representation of the Rainbow in Daralei Cultures

Rainbows have had a number of implications in several Daralei cultures. The most common use is to represent good luck. This belief has developed on it's own among several cultures, including Halfling, Naga, Gnomes, and several others. Rainbows have also been used as a sign of unity in direct relation with diversity (Elven) and the presence of good spirits and other favorable religious blessings (Orcs and Goliath). One group, the Firbolg, believe it to a bridge to the afterlife, crossed by those who were kind and good in life into paradises of bliss and peace.
However, the common interlinking themes of the rainbow between every culture in the world seems to be change, especially for the better. It is believed this concept was developed from ancient peoples who would live out in storms without cover or shelter. When the rain ended and the danger subsided, the rainbow was there as a sign of better things to come, and as many things do when creating traditions and superstitious representations, became symbolic for said good changes and new times of peace.
Due to it's association with change for the better, the rainbow has been adopted as an icon for several groups who call for the equal treatment of all groups and walks of life. The most memorable of these were the World Walkers of 19,412 who made one of the most radical changes in the Daralei Pact since it's conception for the equal treatment of all races. They not only did they successfully push for the banning of slavery in all pact-allied governments, they also greatly influenced the creation of the All Love act and paved the road later for all Equalists to take root in the government and eventually grow to be the predominant force in the pact.
To this day change, love, kindness and freedom are all associated with the rainbow, and it's iconography is still rooted in many cultures and political parties.
