India. The king of bears, Krishna was once suspected of killing Prasena for the gemstone Syamantaka. It turned out that Prasena had been killed by a lion that took Syamantaka, and that lion had been slain by an oblivious Jambavan. Krishna tracked down and fought Jambavan for the gem. The fight lasted for three weeks, at which point Jambavan finally realized who his opponent was and why he was fighting, at which point he surrendered the gem, and offered his daughter Jambavati in marriage.
