The Aftermath of War

The battle between Elysium and Gravestone ended shortly after the death of Carolus. Zane gave the cultists an out, despite the fact that their infantry was surrounded by his horde, and had sustained heavy losses.

Not only that, but the number of casters and archers that had survived among the crusader's forces had been nearly devastated in their entirety. Out of the 5,000 soldiers brought to Tahoe by the Cult of Elysium, maybe a tenth of them had survived.

The only reason the cultists surrendered was because Zane showed them the head of their commander. After enduring such a loss, the more rational members of the crusading army threw their weapons by the wayside and got on their knees, fully accepting that they had been defeated.

Why had Zane not entirely finished off the enemy army, despite his own forces being reduced to around 20% of their original numbers after emerging with a Pyrrhic victory? Because he didn't want to start a blood feud with Elysium.
