Zorian opened his mouth to answer ‘with the aid of the time loop, duh’, but then quickly closed it again. According to the matriarch, this invasion had been in the works far before the start of the time loop. Clearly, someone associated with the invasion got brought into the time loop eventually and started feeding information to them to make the whole endeavor scarily effective, but what about before that? Without knowing exact locations of Cyoria’s defenses, their initial bombardment would have been a lot less damaging than it was. Without knowing the Academy’s exact ward scheme and how to bypass it, their assault at the place would be practically doomed from the start. And on top of all that, the matriarch claimed the aranea were successfully keeping the invaders out of Cyoria’s underworld before the time loop. So really, the invasion never really had the chance to take control of the place.
«Perhaps they didn’t,» Zorian said. «Intend to conquer it, I mean. Cyoria is pretty important to Eldemar, but it’s not the capital, nor its industrial heartland. It’s the seat of Eldemar’s Mage Guild and the home of the world’s most prestigious mage academy, neither of which is likely to cooperate with the invaders. Most likely, they just intended to do as much damage as possible. Keep Eldemar’s magical might busy while they invade with the bulk of their forces elsewhere.»
[You’re very close,] the matriarch said. [They were indeed trying to cause as much damage to the city as possible, but it was to be much more than a simple distraction. Apparently, the date of the summer festival is very magically significant. It is the day of the year when the barriers between planes of existence are the weakest. In fact, the weakening starts exactly one month before the date, gradually reaching its peak on the day of the festival. And this year’s summer festival is even more special than usual. I’m afraid that us aranea don’t know much about astronomy, seeing as we live largely underground, but apparently this year’s summer festival includes some kind of… ‘planetary alignment’?]
Zorian took a deep breath, a shiver running down his spine. Of course! How could he have missed it till now? This year’s planar alignment, signified by several planets aligning with their own, an event that took place once every 400 years or so. The last time such an event happened, a city of mages took advantage of it to teleport their entire city all the way from Miasina to the southern coast of Altazia, performing the largest feat of trans-continental teleportation to ever be recorded. If someone wanted to mess around with space and time on a grand scale, this was
«Yeah, that
[No. First of all, they intended to summon a large amount of high-level demons to help with the invasion. This was why they were willing to go through with the attack, despite their lack of success against us and their inability to do much to the academy and its wards. Demons, especially high-level ones, are virtually immune to mental attacks and highly resistant to magic. The aranea would be massacred in no time at all, and the mages would be too busy fighting for their lives to help out the city’s mundane defenders. Those same defenders would be up against trolls and fire elementals, who are immune to firearms, with winter wolves and iron beaks acting as support.]
«That… that’s horrible,» Zorian said after digesting that for a second. «Why aren’t they doing that now?»
[They can’t, remember? No summoning anything while in the time loop. The whole material plane has been cut off from the spiritual ones,] the matriarch reminded him.
«Oh yeah,» Zorian said. «I guess that would throw a serious wrench in the works. I wonder if they actually went through with the invasion during the initial restart when they had no agent inside the time loop. They would have surely known their plan was doomed without demonic support.»
[They probably would,] the matriarch said. [The demons were ultimately a distraction, same as the rest of their forces. The invasion leadership didn’t actually think they were enough to do more than cripple Cyoria and they wanted it completely wiped off the map. No, the real target lies with the area around the Hole. While the defenders were busy fighting for their lives, a group of mages would secure the place and enact a grand summoning ritual.]
«Ugh,» Zorian grunted. «Let me guess: a really big demon.»
[No. They wanted to summon a primordial.]
Color instantly drained out of Zorian face. «What!? But… that would leave the whole city a lifeless crater! What about their own forces!?»
