To deal with he Megarachnids they used a Dark Magic plague. The plague was spreading through the entire planet, and the megarachnid population, including the queen, would be dead within a few hours. Most ponies have withdrawn from the surface, with only Pegasi and battle mages remaining. The Lance Humans were simple to deal with, a few psi-blockers had been issued to elite pegasi and they had gone on hunting teams, quickly and easy dealing with them. Patrols are assigned to the treetops, slowing down the surprise attacks. The Saeva Simus aren't given any special conditions beyond wookie trackers being issued stealth talismans and hunting them down. Pegasi equipped with Short range but powerful EMP cannons as well as explosives are sent to hunt down mech warriors.Also to decrease the chances for the forces to escape all ship traffic to the planet has been halted, besides a few exclusive transports that have randomized routes with personnel equipped with psi-blockers and genetic readers.

Unfortunately for the Equestrians, while the majority of the megarachnids were dead and likely the Equestrians thought they had all died, a single one had survives due to a random genetic mutation conferring immunity to the magical plague. Hiding within the hole, she began her metamorphosis... If she produced offspring, they would invariably share this mutation: Survival of the fittest

The Lance Humans were seemingly easier to deal with than the Equines suspected, and they continued their push as the Lance Humans retreated... Only to feel a barrage of bullets from the tree tops, bringing parts of them down. Then they would feel a weight on them as the Aru'Shumi launched down on them
They struggled to toss them off, but the strange, carrion bird like alies slit the pegasi throats, sending them crashing to the floor as they buckled. The aliens did not stop there, they tore out the organs, devouring them and breathing in the rich stink of the bloody corpses. They were like hungry wolves around a helpless animal. The Lance human group they had been chuckled darkly.
This was generally the fate of these elite pegasi, put down by surprise attacks from above. Over confidence had been their downfall, expecting they would be able to quickly defeat a force that was entrenching its self in the jungle and being overly aggressive. Grave tactical errors were made, and it usually gave the Ari'Shumi a chance to drop in and mess up the Pegaso

The Saeva Simius were losing at first, but once they discovered the Wookies were using stealth talismans their tactics changed, relying now on placing traps and waiting for the Wookies to activate them, killing them. They would then attempt to salvage the Wookies stealth Talismans Regardless, it seemed the Saeva Simius, for now at least, were not seeing the success of their Aru'Shumi counter parts.

The mech soldiers put up a good fight, but unlike the others they were illadapted to hiding in the forests, and generally being more durable than the Saeva Simius didn't make up for being exposed versus a larger force. Eventually, they all retreated to the hole to hide away

The eyes of the Triarian glowed a dull orange as he assembled the machine before him in the newly constructed third chamber. The third chamber had more, and larger, holes than the first, pointing to the surface in various directions to allow for the weapons firing. It was more like a dug out than an underground chamber, so this one would be much easier to find once it started firing. Its connection to the other chamber was by a large, winding passage way which the Collective wished to ambush their enemies in should it be discovered.
