Sailing
First off, boats, the player would be able to make ships, these would only require a bunch of logs, but also can hold cannons which are made of steel and need ammo (also made of steel)
When used in water, it would have two times the speed of an experienced swimmer.
But be careful, since if the logs you used to make the ship weren't treated properly (AKA, they weren't high quality logs), your boat would have a chance of breaking, and would be weaker in general.
Pirates
Of course, if you have something, criminals will want to take it from you, and that is the case with pirates.
Pirates would behave similarly to bandits, except instead of just bullying or attacking if you are really stubborn, they straight up storm your ship, grab anything you have that has any value to them, and kill the crew that shows resistance to the attack.
If an attack is successful, the pirates might decide to take control of your ship.
Continents
Now, if you had this incredible sailing ability, what would you do with it? Well, you probably would explore deeply the unexplored, and, if you have a similar fate to the real world's Cristopher Colombus, you might find a new continent!
But, first, what is a continent?
Well, i say that continents should be randomly selected chunks of the map, that have the requirement of containing a huge landmass, a regular world should have around 4 to 7 continents.
But continets need names! How would continents be named? Well, i propose that before discovery (i'll explain how i suggest discovery works later), the continent is named after a piece of culture (be it a hero, god, monument, etc) of the dominant native civilization of the continent (AKA, the one that controls the majority of the land in the continent), for example:
Main god of the dominant civ's pantheon: Ashurath -- Name of the continent: Ashurathia
After discovery, the continent would instead be named after the person that discovered it, so it would look like:
Person that discovered the continent: Moldath -- Name of the continent: Moldathia
Discovering Continents
But how does discovering continents work?
Well, there would be a list of requirements, if these requirements are met, then it is a continent discovery:
1. The discoverer must be from a different continent to the one he's discovering
2. He must be the first foreign to reach this continent
3. If a party that fullfills both requirement 1 and 2, the discoverer is the first one of the party to geographically enter the continent
When a continent is discovered, the legends entry of the character and the legends entry of the continent should say:
At *Year* *Season*, *Discoverer's Name* discovered *Continent Name (Post-Discovery)*
