Chapter 2: What if the first contact with the Tigianis gone wrong

As soon as he opened his eyes, Captain Sartus ordered, "Set the course."

Captain Sartus crossed his hands behind his back and mentally prepared himself for possible combat and earn the glory for the Turians. Within the next second, Honorable Eye and other four insignificant but armed ships gone to Relay 314.

And only to crash right into an extremely large ship's front with minor explosion (in giant ship's point of view), causing the unknown ship's captain to perceive this crash of four "projectiles" to be some sort of trap set by unknown, hostile race. Never mind that the ship is located too close to the Mass Relay.

Couple days later…

"-our weapons are having absolutely no effect on their armor! Streets getting filled with destruction and corpses of our people!" An explosion occurred, followed by a Turian officer who continued to update with his Omni-Tool, "Spirit! We can't hold them off! They're even stepping on our tanks! Our spirit-damn tanks!" Another explosion occurred, ending an unfortunate Turian officer's life.

An Asari, in military uniform, turned off the recording and spoke to three quiet Councilors, "This is the last report we were able to get before we lost another planet to these giant invaders."

A Salarian Councilor Valern asked, "These giant invaders…Do we have any idea about their capability?"

"Aside from being aggressive with their rifles packing more firepower than the tanks and a single armor of unknown material withstanding two squads of Turians firing, the invaders have displayed their physical strength." At this, an Asari used her Omni-Tool to show a recording of a single giant physically throwing a dropship at a Turian squad, crushing them with only one survivor who barely survived only to get crushed by a crate.

"Although the weapons are still capable of hurting and sometime, killing, they still have to have the supports from armors, air, and even, space. Unfortunately, for every Giant killed, it still managed to kill over twenty-five Turian and caused destruction of tanks. And they seem don't mind…eating Turian, in addition to…us."

"Enough and don't bother with that recording." Tevos said as she rubbed her temple. Like the Turian Hierarchy, the Asari Republic has lost few planets while the Salarians lost three planets and one space station to the dubbed Giants.

"Do we have any understanding of their language?" Tevos asked.

"No, ma'am. The experts are still unable to translate. Their language is too foreign, they said. Though…" An Asari look at Sparatus, "They do sound similar to the Turians, only deeper."

"What about their ships?" Sparatus asked.

"Their biggest ships are longer than the Citadel's arms while the smallest ships that we were able to see are still bigger than Destiny Ascension. Their firepower, compared to our-"

"Say no more." Sparatus stopped an Asari from going on with the report. A Turian Councilor is silent, thinking. Until he said, "The Treaty of Farixen."

"Hmm?" Valern look at Sparatus, who clarified, "We're going have to momentarily take the treaty out of effect to build more dreadnoughts for firepower. And we'll have to issue mass draft in addition to researching the Genophage…"

"You-" Tevos began but paused to think about Sparatus's ideas.

"I concur." Valern spoke in agreement with Sparatus and added, "Though, with their full body-armor, obtaining the sample will be difficult…"

"Tevos?" Sparatus stared at Tevos, who after thinking, nodded in agreement and said, "I too concur. We will have to show them that we are not food. But…We'll have to work with the Batarians, Terminus, and Quarians."

And thus, the Citadel military has begun to utilize aggressive tactics to kill the Giants, though the Giant ships have proven to be formidable, even when being outnumbered considerably. The Citadel stealth ships were able to sneak into the Giant ships' glaring open gap to attack the power core at the cost of their lives. The Citadel military called it 'the Sneak-In Destruction' tactic, a tactic that was first used when a single Giant ship accidentally found the Citadel and few Citadel ships, under guidance of a Turian captain, managed to locate the open gap and navigated through the Giant ship

To the surprise of the Citadel races, the Geth and enigmatic Collectors joined to fight the Giants' advancement. However, the Giants continued to overrun the planets after planets, causing countless death of civilians and military. Furthermore, the Citadel military was unable to find a single Giant planet.

The odds against the Giants improved when the Collectors prematurely woke the ancient machines called the Reapers. Or the Old Machines by the Geth. Because the Giants were causing too many casualties in current cycle, which would mean less 'materials' for the Reapers to construct for the next cycle, the numerous Reapers joined.

And since the Collectors failed to disclose the fact that the Reapers are the genocidal machines and were responsible for causing countless genocide per cycle, the Citadel welcomed them, despite their paranoia of artificial intelligence. But again, the Giants were killing too many for the Citadel to turn down the help. It helps that the Geth too didn't disclose the fact and the Reapers helping to move the Citadel station itself to different location.

Slowly, the Reapers were able to indoctrinated a small percentage of the Giant soldiers and strategically have them in position to betray their kins. Not knowing this particular ability of the Reapers, the Citadel forces went on more aggressive strikes before finally located one of the Giant's planets.

That when the galaxy become bigger than ever with the Giants revealed to have allies of different races, all similar sizes. All with gigantic ships. In the end, the Reapers too wondered how the Giants exist.
