The Sun Chariot had a coachman and a mount, which were Weaver and Aroman. However, Wayne's abilities were too uncanny, and to prevent the two Subsidiary Gods from becoming liabilities, Galle did not summon them into battle.
Furthermore, as agreed before the fight, it was a one-on-one duel, accepting defeat with grace if one were to lose.
Once the Sun Chariot started, it wouldn't stop, streaking through the skies above the sea of fire like lightning, tearing through space, dragging black lines and strangling the rising white froth steam into ash.
Galle could clearly perceive that these vapors were highly active. If they were not eliminated completely, Wayne could resurrect at any moment.
In the blink of an eye, all steam was burned to ash, leaving only the last wisp lingering in the air.
