Of the fourteen elven kings of the Lignum world, 7 of them have died in the six months that the invasion has lasted.
The remaining six of them put up a front to make it look like they are the last elven kings left. They did so and hoped that the humans would bring out a new tool or overplay their hands.

It wasn't until a new variable appeared that they couldn't deal with that they played another card and revealed what else they were capable of. At this point, it is getting on the elven kings' nerves.
The demigod that was being besieged by two indescribable combat bots roared in anger and lamented, "What kind of terrible enemy have we encountered? What did we ever do to deserve this?"
