A while back I came across some interesting info on a Predator fansite about the name Raphael Adolini 1715, which was engraved onto the flintloack pistol that the Eldar gave Harrigan at the end of Predator 2.
" According to a Dark Horse story Predator: 1718, which features in Decade of Dark Horse #1 (of 4) and the collected edition Decade: A Dark Horse Short Story Collection TPB, the pistol was a trophy taken by a Yautja who hunted a band of pirates in 1718. "
" As the story goes: dropping anchor at an island in Guinea in 1718, the Captain of the small band of pirates suddenly faced mutiny over a stolen case of gold which was destined for a church. The Captain wanted the gold returned, much to the anger of his crew who turned against him. In the following battle, a watching Predator joined the fray and fought back-to-back with the Captain - attacking the rebellious crew with an extendable sword.
In the climactic scene, with the crew dead and the Predator and Captain about to battle mano a mano, the Captain is suddenly shot in the back by the last member of his crew, who was in hiding. Denied his trophy, the Predator angrily blasts the final crewman to hell. With his dying breath, the Captain whispers 'take it...' to the Predator, throwing him his beautifully engraved pistol. With the Captain dead, the Predator takes a moment to think about this battle - and with some curious respect, leaves the dead Captain his extendable sword... 'Take it.'
The final scene sees what looks like a shooting star moving across the evening sky, far above a now silent island - and a pirate ship in the bay, never to leave anchor again. "
