Levelling Mars: Book 3: Vanquish

Book 3 sees the crew of the avatar mission struggling for survival. They have just been forcefully evicted from their base and attacked on their way to their backup location. They had taken one of the alien biomes and now need to defend it at all costs. If they fail then they will not survive.

If they succeed then they need to take the fight to the elven overlords and their orc mercenaries. Will they be the vanquishers of the vanquished?
