Spitball #1:
Its been a few years.... There was a major score in the city of Holvikstad - a merchant flush with cash and treasures had just returned from overseas. Before it could be spent, divested or safely squirreled away, two gangs of ne'er-do-wells planned a strike. Krisanna and Lothar were members of the different gangs. When the heist went down, the groups met and clashed in a mildly epic fracas that destroyed the merchants sumptuous dining hall and left all the other members of the two gangs dead or bleeding out on the floor.
Exhausted, slightly wounded, and pressed for time, the two agreed that splitting the haul two ways and getting out while they still could was an amicable arrangement. A night of celebrating followed, during which time the two established a mutual respect and laid the foundation for what passes for friendship in their line of work.
Since then, they have crossed paths maybe once or twice, although always in passing, and have joked that one day perhaps they'll work the same side of a job.
