Custom among pirates to yearly vote for their leader. If a majority believed the leader was doing poorly they could hold another vote. Democratic except in times of battle and danger at sea. Could bleed that over to some 'honorable' bandits.
A comet flies through the sky every so many years. During this time no fire is able to be lit anywhere the comet is visible.
Sword sharpness is equal to the status and skill of its wielder.
After killing certain animals, if you drink their blood while performing a sort of ritual you will have visions and/or gain specific powers for an amount of time.
Good luck to drink out of wolve's paw prints or some other animal. Gives special powers.
Swords form a bond to their wielder. A symbol on the grip that is absorbed through the user's hand and appears on the back of the hand. Maybe only visible to them or others that have the abilities. Could give unique powers depending on when it happened and what they did to get it. It takes a specially made sword that only few can receive and made by a certain race. Then they must do something really heroic to unleash the swords power. Once unleashed it is theirs till they die then the sword goes dormant again till another accomplishes another feat.
People that live in cities no longer have any contact with the gods. There was a pact between the gods, humans, and animals. We could talk to the gods and the trees were the witness' to the pact. When the trees started getting cut down to make cities the pact was broken by the destruction of the witness'. So now only those that live with nature can speak to the gods and/or animals. Some trees grow tall creating darkness that scares men and they are not able to go near them. If they could they could again speak to the gods.
The journey had been a long one and now they had entered the mountains. After an entire day spent on paths cut into the mountainside and through moss covered coniferous woods, they encounter a desperate young mountain tribal. He is searching for his beloved wife and his elder brother, both of whom he got separated from after an unsuccessful attempt to kill a cave bear. The last thing he saw was the cave bear in full pursuit of his wife. He could not help her as he had been knocked to the ground by the raging beast, and was struggling to regain full consciousness. The tribal will be clearly nervous and urges them to look for his wife during their travels. He will stay in his village a couple of miles to the north and pleads for assistance should they recover his wife, whether she be dead or alive.
On the next day of travel, they will journey upon a dim track in the forest and while they are preparing to ascend another path cut into the mountainside, they hear moans of lust from somewhere nearby. Upon closer inspection they will spy a young tribal woman in the heat of the act with an elder tribal male. They are consummating their forbidden love on the cold mountain moss, and beside them lay the skinned and slaughtered carcass of a huge bear.
