Dart is a foulmouthed pirate, but is kind and extremely loyal to those he puts his trust in. Years ago, an amnesiac Dart washed up on shore, injured, but none of the villagers would go near him as it was during a religious holiday in which it was taboo to touch blood. Captain Fargus and his crew finally picked him up. He became an amnesiac, was given the name Dart, and soon became Fargus' most trusted mate. Might be Rebecca's brother Dan but this is unknown for certain.
