Fiers

Fiers is a dwarven planeswalker, revered as a god by Dominaria's dwarves and Barbarian tribes on Otaria. He was summoned by Karona as the deity of red magic.

Fiers is part of a heavily-debated continuity issue, along with several other popular characters. While Karona spoke with Fiers during the novel Scourge, the meeting was later retconned, though no explanation has ever been provided. It is possible that Fiers is indeed a planeswalker, but if the retcon is to be believed, then the real Fiers has yet to appear in any novel.

In the "Myths of Magic", Fiers is a god who helps Gaea build the world. In the short story 'The Lady of The Mountain' it is said that he made all dwarves and helped create the Lady of the Mountain. However, few dwarves other than Otarians appear in the storyline, so it is hard to say whether or not this tale is true and all dwarves worship him, as stated in the short story.
