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.
For those of you who don't know, I have been sick with something for the past month or so. Yesterday I finally went to the doctor, and they put me on a variety of drugs, one of which has side effects that cause me to be fatigued and drowsy. So until I get over this illness, I'll probably only be releasing one chapter for this story a day. Thank you all for the support you have shown so far.
