Info
The great Ravine has shown many of its wonders to its first explorer, the Sironian SirBowi. He was exploring the borders of the known World before stumbling upon the place. Seeing riches deep down near the bedrock he decided to go down into the Ravine. Suddenly gravel started to rain down into the ravine, narrowly missing the explorer. Soon after that Lava started to flood into the ravine. At this point SirBowi knew that something was up. He quickly got out of the ravine only to be greeted by screams, seemingly coming out of nowhere. It was spoken in a language not being able to be comprehended by mere mortal beings, but he understood what the Ravine wanted! It was promising Greatness. Soon SirBowi started to throw offerings into the Ravine. A heart of the sea responed in the appearance of water, soon filling up with drowned. An offering of diamonds resulted in zombies in diamond armor appearing. An offering of Emerald caused the Ravine to expand a few blocks. SirBowi put up an offering of different blocks of ore next to the Ravine, containing coal, diamond and lapis ore blocks. The Great Ravine took them as an offering and turned them into blocks of sand. A makeshift protective shelter was built around the Sand. End Portal Frames were also discovered in the waters. Soon the tales of the Ravine were spread by SirBowi.
