On the vast wilderness, an iceberg stood majestically.
Such icebergs are common on Ganymede. This is because Ganymede has abundant water and extremely low temperatures.
Compared to ordinary rocky peaks, these icebergs actually have a very short lifespan. Due to internal geological movements within Ganymede, ocean currents beneath the thick ice layers, frequent asteroid impacts, and tidal gravity from Jupiter, such icebergs might form in just a few thousand years and then disappear in only a few hundred years.
But at least while they exist, they stand just as majestically and are as indestructible as rocky peaks.
The iceberg in front of them was over a hundred meters tall. It was composed of ice even harder than rock. Because it was mixed with many impurities, it appeared entirely black, looking as if it were cast from steel.
