VYASA
Vyasa appears for the first time as the compiler of, and an important character, in the Mahabharata. Actually, he was the expansion of Lord Vishnu Himself who came in Dwaparyuga to make all the Vedic knowledge available in written form which was available in Sound form at that time. He was the son of Satyavati, daughter of a ferryman or fisherman, and the wandering sage Parashara (who is accredited for being the author of the first Purana: Vishnu Purana). He was born on the meet of two rivers Seti and Madi. The place is named after him as Vedvyas, possibly the modern-day town of Damauli in the Tanahu district of Nepal. He was dark-complexioned and hence may be called by the name Krishna (black), and also the name Dwaipayana, meaning 'island-born'.
