Io is paired with Chronepsis, who is seen as a re-enfolding that balances Io's extension of being into the worlds. As Io becomes all things, Chronepsis draws them back into himself. They are seen as brothers and represented in a complex symbol involving a nine-headed dragon swallowing its nine tails. Like Jazirian, Merrshaulk, and Shekinester, Io is an aspect of the World Serpent archetype.
In many campaign settings, the draconic pantheon of gods consists of the leader Io, as well as Aasterinian, Bahamut, Chronepsis, Astilabor, Hlal, Lendys, Faluzure, Garyx, Tamara and Tiamat. Aasterinian is his messenger.
Nathair Sgiathach is also said to be an offspring of Io, though he has no involvement with the rest of the draconic pantheon.
Some myths say Io raised the kobold god Kurtulmak to divinity.
