Have you heard of the Sapphire Radiation? While it's considered less harmful than standing next to a microwave, or talking for long on your cellphone, Oberon has received a lethal dose, which also sterilized him. Some have referred to this as "poetic justice"...whatever that means.
Despite this, Oberon remains Darkshines most eligible bachelour. He enjoys getting lost on long walks, spending time with his pet giraffe, watching Home Alone, and reading body building magazines.
Many have speculated about his love-hate relationship with Balur; while we may never know the details, Balur is on record as saying he will never adopt, especially "...with a man who never puts the seat down, because that's just nasty!".
After watching a documentary on hyenas on his 32 inch crystal ball, Oberon became reclusive and paranoid, killing and eating his six brothers - Hammel, Camel, Mammal, Pajammal, Ohdammal, and Chip. He has no other living relatives, but indicated in his last public appearance that he is "optimistic about the future, and in a much better space".
Unfortunately, Darkshine is approximately 3.1 million years and two alternate dimensions away from discovering artificial insemination or cloning, although Oberon has hired an Ice Dragon, and indicated that he will go the Walt Disney route if he has to.
According to the latest postings on Wikileaks, his most likely successors include Emperor Shin, Julian Assange, Test, and Valdimir Putin.
