Yrdon was the first creation of Veza and Umumtu. He lived for millenia, kept alive by Veza's Life Force. Little is known of his life, but it is believed he was close friends with both Veza and Umumtu.
He is accepted as the first, and wisest of all the Dragons. It is said that he taught Elves writing, Orcs honor, Gnomes science, and Dwarves engineering.
At the end of his life, Yrdon was offered to be saved by Umumtu, but he refused. He said he was looking forward to meeting Mother Death. It was his death that spurrned the rift that lead to the World being Sundered.
