This quest can be started at Kaer Trolde harbor by speaking to a Skelliger man. He identifies as Johann Bohner, and asks Geralt for a loan, having been shipwrecked and left with no money for his trip back home to Novigrad. The man promises to pay back every last copper should Geralt pay him a visit in Novigrad's Port District. You may give him the loan of 150or refuse.
If given the loan, the man travels south of Kaer Trolde harbor, though not very far. He can be encountered again on the road south out of town at a trading post, just north of Crossroads. This time, he is posing as a wandering juggler from occupied Temeria. When questioned whether he is actually from Novigrad, he claims that he, in fact, hails from Maribor. Geralt catches onto the bluff rather quickly, and compliments the man on having such a great short-term memory. The man pleads Geralt not to turn him in to the jarl, and still promises to pay him the money back later, with interest. Should Geralt refuse the man's plea, he will resist and attack at which point the quest ends. Otherwise, one could opt to "take care" of the man himself, or let him go.
If let go previously, the Skelliger can once again be encountered in the village of Fyresdal, which sits at the bay's mouth on the southern coast of Ard Skellig. Here, the witcher's patience is rewarded, as the debtor pays back the loan as promised plus interest, for a total of 200, resulting in a net gain of 50.
