Creation according to the rules is a flat earth world but what of the earth below it and the sky above? If there is a Pole of Ice in the north it makes sense there would be a Pole of Air in the Sky. Far in the night sky are portals to Yu-Shan held an infinite distance from Creation that were accessed Starships in the First Age. Sidereal Martial Artists can leap through these portals to enter or return from Heaven.
The ground near the Elemental Poles isn't necessarily the same aspect as the Pole, there isn't thousands of miles of ocean around the Pole of Water. The season of an element is the time when it's Pole Essence is strongest and flows through Creation rousing Elementals and empowering them. They naturally regain the most Essence during their Season.
The actions of Earth Elementals are characterised by massive effort over extremely long ages, but when they act the effects are cataclysmic. Earth Elementals can move whole continents, cause massive earthquakes and raise mountain ranges or open vast chasms.
