[Medieval Fantasy] Guilds historically prevented non-guild members from practicing a trade. Does this hold true for the various Heroes Guilds I keep seeing everywhere? What happens if I go out and slay a dragon without a guild membership?

Good luck *selling* all those dragon parts. Or finding someone who will help you haul that giant carcass back to town. The Guild is essentially a giant worker's union. In some places, it may be the only option, and trying to buy and sell things, or even general *hero* work, without Guild backing might actually be illegal.
