Technological achievement
Although it did not survive to this day, records tell of the Celestial Column. A device that supposedly allowed the gods to share their power with mortals. According to the surviving records, this was used as a way of bridging the understanding between gods and mortals.
Many gods are ascribed to having risen to godhood after having received power for long enough periods through the Celestial Column, and Niko quickly grew to be the centre of the civilization of E'ath. Here trade flourished and each individual was empowered to undertake whatever tasks they wanted to achieve. The Celestial Column is even theorized to have been sentient and been the de facto ruler of the city in the few decades before Li'minar fell.
