Pirates.

All the pirate captains introduced themselves to Rasmus and the names of their pirate crews. Rasmus got the gist of the hierarchy of pirates from them based on how long they had roamed the sea and how many crews they had. From that information, he knew which crew was the strongest among the seven.

The first and the lowest rank among the seven was Matthias, the Big Belly with twenty-four crew members. The second among the seven was Rosalind, the Pale Snake with twenty-seven crew members. The third among the seven was Marigold, the Iron Fist with twenty-nine crew members.
