He and his family owed a great obligation to Yennefer, as she helped them during the pogrom in Vengerberg. Because of this, Molnar provided assistance to the sorceress in any way he could. He stored and delivered letters to Yennefer, and offered her unlimited credit with no interest.
Just before the banquet-turned-coup on Thanedd Island, he made a 1,500 oren donation to the Temple of Melitele in Ellander, made an anonymous 2,000 Novigradian crown payment to the school of Aretuza for Ciri's tuition, and provided Yennefer with a banker's draft worth 500 crowns, all done at the request of Yennefer herself. He also offered to cancel a debt worth 100 crowns incurred by Geralt in Dorian, but Yennefer objected and instead proposed that he raise the payment for Geralt's contract in Hirundum.
