Monsters, such as hydras, chimeras, dragons, etc., exist in this world. They plague humanity with random attacks, with certain empires suffering more from these attacks than others. States refrain from using their military to fight them because the army is used to defend against external threats, and can't be deployed every time a new monster pops up. Instead, they gear toward hiring monster hunters to take care of the problem. These hunters are valued because of their experience with handling these threats, or have abilities that are magical in nature. They are often trained by guilds funded by states, and are given licences to work after they complete their training. However, they operate as independent contractors.
The job is obviously a dangerous profession. Hunters risk being burned alive by dragons, crushed by giants, tortured to death by psychopathic elves, eaten alive by gigantic, hungry hungry demonic hippos, seduced by sex-starved nymphs and never be seen again, or worse. Hunters want to ensure that they would be receive benefits should they get hurt or disabled, or that their loved ones would be taken care of if they get killed. A system has been installed by the United federation of guilds, a conglomerate that operates independently from kingdoms. This system keeps costs relatively low while providing a form of insurance to the hunters. They earn a fee for every monster they kill: the bigger or more dangerous a monster is rated, the better the pay. A small percentage of their fee goes back into the guild treasury to handle expenses, paying for staff, care for hurt adventurers, etc. In addition, each hunter is required to pay a premium every month that goes toward their life insurance policies. The more expensive the policy, the bigger the payout in case of death.
With these rules, would insurance become a market for monster hunters?
