Title says all you need to know.
Once upon a time, there was a human that decided to go on an adventure! Now, while this is quite common, so is the rest of the story. (Which happens to take place in a world that I ramped all of the monster/megabeast/nightcreature settings way up.)
This human found two companions within a small fortress, and heard rumors about a werebeast in some cave towards the south. This adventurer wielded a bronze sword and shield, one companion had a copper crossbow, and the other had a silver pike. On the way towards the lair of the beast, night fell, and with night came a pack of dingoes while the three adventurers slept! Before being awoken by the noise, the man that wielded the silver pike had his throat torn out by the dingoes. 5 of them our adventurer counted, and 4 of them he killed, as he only allowed the crossbowman to finish off one that was severely crippled.
But they must go on.
Upon entry of the lair during the following dawn, the two adventurers set eyes upon a fiendish looking beast in the shape of a giant mouse! The weremouse quickly jumped at them, but the two adventurers quickly dodged out of the way. The beast is dodging every strike, he parries to the left, the adventurer counters to the right, and he catches him in the neck! Only managing to tear the fat... The beast realizing that the crossbowman is a much easier foe charges at him, knocking him down and biting him through his sleeves and through his muscles and arteries. The swordsman stomps on the beast's foot, shattering the majority of the bones within, and finally shoves his sword through the beast's head. The crossbowman stands and gives the original adventurer a wary look.
He knows that he now carries the curse.
With a slight hesitation, the adventurer swipes towards the cursed man, but misses. The cursed man wastes no time, however, in placing a bolt through the adventurer's kidney. But who needs a kidney? In just one more strike, the adventurer decapitates his former comrade. The now lone adventurer sets forth to another near-by fortress. Upon entering the gate though, he was not greeted with open arms. Behind the gate were two human archers with arrows pointing to the adventurer's head, and death in their eyes. One in the heart, and another in the guts is all the reward that this adventurer gets for killing such a vile creature. Such is life when one seeks fun.
