the swarm has all the markers of a edritch abomination, it is the other, its is hunger without end, but whatever is in the core hits some of those points as well but its morality seems to be a bit more in our favor.
honestly i think its the crimson order who does the ruling in place Tinkizar, either because he dead or to far gone from the swarm infection, it might explain why no one has ever seen him. the swarm its self could be be something like New Phyrexia, the absence of the gremlin king could explain why emberlight even exists, it might even part of the reason why punch and vise have no problem helping us out (for nice prices of course)
but don't you just love how heroic the echo logs makes us sound
Edit @Eltia
from the echo logs the cradle was created to protect what ever is in the core , its made from multiple worlds. but the architect (the gremlin king we think) lost it. we are only here because we crashed and are stuck, thats why every new knight gets orbital dropped into the cradle
The Swarms were the native, intended beings gave birth by the Cradle. But the Creator intervened and seeded the various species (Gremlins, Strangers, Snipes) onto the planet. This was done by using the power of the Core to suppress the spread of the Swarms, so the Creator's beings could prosper and maintained Cradle for the Creator.
After Spiral Knights crash landed on Cradle, they were drawn to the power source of the Core. In one of the tests, they temporary weakened the power source in the Core and awakened the Swarms. The Swarms spread quickly and corrupted everything in their paths.
The only way to stop the spread of the Swarms were through isolation (through locked gates) and restarting the suppressing system at the Core. But it's too late, because the Swarms have started infecting the Core, transforming into a new monster unseen in the history of Cradle. Would the Creator interven one more time? Or would the destiny of Cradle lies on the shoulders of the crash landed Spiral Knights?
We will find out in Tier 4. a.k.a. The Core.
P.S. OOO, please make the story not suck. You can do better than an amateur, right?
