I gathered all evidence to his affair and yet he's still putting a fight! Portrait, letters, costume, trusthworthy witness. All proving that elf Mafinor has an affair with beatiful dwarven lady.
Check the fight what more you would expect?
It's well known that dwarves males and females are not easy to be distinguished. Even here!
(BTW it's strange like demons from Atrixus keep their word, whereas from Helvedia not.)
