Catoblepas

Catoblepas Legends tell of a human herder who bragged that his cattle were the finest in all of Theros. When the gods heard this, Heliod, Nylea, and Mogis became involved in laying a curse that afflicted the mortal and his cattle, giving rise to the first catoblepas. How the gods were involved, though, and for what honorable or petty reasons, the gods’ faithful—particularly those of Heliod and Nylea—greatly debate. Regardless, catoblepases are widely viewed as cursed creatures, which only Mogis’s faithful hold in wicked esteem.
