The following article/section is from the Storm Runner/Shadow Bruja continuity under Rick Riordan Presents and not the Riordanverse canon.

Chaac ("CHAHK") is the Mayan god of rain, thunder and lightning.


Chaac uses a lightning axe to strike the clouds and produce thunder and rain. According to one myth, he defeated his evil adoptive parents with his brother, Kinich Ahau, the god of the sun. But then he committed adultery with his sister-in-law and is punished, his tears of regret became the very first rain.[2]

Chaac was honored in three months of the Haab' calendar. In the month of Tzec, the bee keeper festival occurs and offering plates with the rims covered in honey and given to the rain god. In the month of Yax, ceremonies honored the god while temples were renovated or repaired as needed. In the month of Mac, elders of the community led ceremonies that honored both Chaac and Itzamna. Fires were lit atop the temples and the hearts of animals were thrown into the flames. Once the hearts were completely burned, water was poured on them as if rain from Chaac had extinguished them.[3]

The Fire Keeper

Chaac is present during the execution of Hurakan along with Ixtab, K'ukumatz, Nakon, Ixkakaw, Alom and Itzamna. He gives a speech reminding and warning the spectators to stay in line. When Bird and Jordan escape and the gods catch Zane Obispo and Brooks, he is shocked to see Ah-Puch and hurls a lightning bolt at him and is shocked when the godborns arrive. In Xib'alb'a, they hear Zane out and agree to pardon anyone they see as guilty and to train and claim the godborns. He reveals to Louie that he is his son and the gods decide to officially claim their children in June in order to find more godborns and keep them out of the twin's hands.
