An oath that offers no hope will only bring despair to this group of wind element creatures, eventually leading to their complete downfall.
To change that is simple: just assign a time limit to this oath, like erecting a lighthouse in a hopeless and dark wilderness, illuminating the path ahead. As long as a creature has a goal, has something to look forward to, it will bloom with hope.
Therefore, Angel decided to amend the oath and added this twenty-year limit.
Initially, Angel thought five years would be sufficient, as these wind element creatures could only provide some assistance in the early stages of pioneering the Tidal World, and their usefulness would diminish afterward.
However, considering the long lifespan of elemental creatures, five years was hardly enough for them to deeply reflect, so he extended it to twenty years.
In Angel's view, this was already quite a long time.
