I did an Eberron one-shot once.

The 6th level trio, a kobold wizard, a human rogue, and a human bard, were in the middle of the ocean, as a storm came in.

They were pirates. And they basically had that little ship that Jack Sparrow had at the very beginning of the Pirates of the Carribean...

Then, in the distance, they saw an elemental galleon.

Obviously, being pirates, they decided to take it over. Only to discover that some OTHER group of pirates had ALREADY taken it over.

So, being pirates, they changed their plans to stealing the stolen ship from the thieves, and ride off into the sunset.

Pretty quick, the bard got separated from the others. Soon I was jumping back and forth from the wizard and the rogue desperately trying to fend off the brunt of the enemy pirate crew using improvised traps, all their resources, and hit-and-run tactics, to the bard following the "story", what with freeing the last remaining pilot, who I played as Dolerous Edd from A Song of Ice and Fire (think Eeyore) and regaining control of the ship with his help. Opposed by a renegade Dragonmarked who abandoned House Lyrander. Who created a storm inside of the ship, which made the bard have to cling to stuff for his life or else get sucked out into the ocean by the wind. While the ship caught on fire.

So, by the end, the wizard and the leader of what was left of the pirate crew had a one-on-one battle to determine who would be in charge of the now-barely-enough-on-both-sides-to-control-the-ship group, and cast his final spell, glitterdust, which managed to defeat his save. I rolled a 1, right in front of everyone, for said opponent. Needless to say, everyone began to hail the kobold as the new captain as the old captain screamed about how blind he was on the ground.

Of course, the second in command druid summoned a griffon and threw the original captain overboard, and proceeded to declare himself the new captain after using contagion to blind the kobold PC. Just in time for the bard to reappear, charm the barbarian third in command, and declare HIMSELF the new captain, and defeat the second-in-command, with the rogue and the barbarian's help.

So... the ship went through four captains in three minutes. Which sounds about how pirate wars of succession usually should go.

Later, of course, in revenge for stealing his captain-hood, the kobold would kill the bard and turn him... into a regular zombie. Not even a special, powerful undead. Just a normal 1/2 CR zombie. But that is another story...

Anyway, it was a very exciting session.
