I saw this idea on one of the Central forums and thought it would be amazing to implement; a side quest that would reward the player with a new, unique Companion based on what world they selected as their hometown.

Pirates who hail(ed) from Grizzleheim would receive a Bear or Raven
Those from Mooshu would obtain a Sheep, or some other Mooshu creature.
Marleybonian Pirates would get a Cat Thug or Cat Bandit, maybe even a rogue Redcoat...?
Those from Krokotopia would have a Krok or Mander minion!
And those from Skull Island would be rewarded with a unique, 'piratey' Companion. Maybe a Wharf Rat Squirt?
