One thing we see a lot of with teh True runes is, as others have stated, balance. Sun and Night are an example. Order and Change are another, The five elements. The ise behind the true runes is that they are the components of the Suikoden world. You need all of them in harmony to exist.patapi wrote:Sun Rune and Night Rune supposedly maintained a symbiotic relationship once. That wouldn't work if the former's power was supposed to so strong that no other True Rune could get near it.
However, manifestations are not equal. We know that the True Runes have a will of their own. They choose their own bearer and we have heard so many stories about various curses associated. The sun rune is an epitome of energy and light. It is simply a more force dominated rune, when coupled by it being unable to be fully controlled by a human bearer, can have devistating effects. Now, based on what we know of say, the Dragon Rune... we know it allows creatures from another world/dimension to exist in this world. It's focus in all likleyhood is not outward force.
A rune's effectiveness can also be determined by the bearer's abilities. Here is where the elemental runes prove as an example. Assuming the Flame Champion is Hugo, when he receives the rune he isn't a great mage and his affinity with the element is average. Put Suikoden III Hugo vs Geddoe with True Lightning or Sasarai with True Earth, Hugo would probably get humiliated. Why is this? Is the Fire Rune weaker? No. But it is understandable that he would have less control of a rune when compared to someone who had it for 50-60 years in Geddoe's case or is particualrly skilled in magic like Sasarai who has had the rune his entire life. That could change over time.
The Sun and Dawn rune existing also does not necessarily point toward the Sun rune being stronger. We have seen offshoots of True runes. Many of the strongest one such as second tier elemental spells, pale gate, darkness, condemnation etc are pretty rare. It is assumed that the star rune is a unique companion to the night rune. Having unique runes borne off of it though is very likely the way to control the sun rune's influences. Much like how the rune of punishment also has the atonement stage and Suikoden 4 introduced a blance chart for the five elements.
So yep, long story short, the Suikoden world is all about balance. Some runes might seem more physically devastating than others but in the end, there is always something that counteracts any great power.
