Theory: Wynncraft Is A 3d Terraria World

Title
My first piece of evidence is that the Nessak Forest stops, or at least slows, the corruption. In Terraria, no matter what mode u are in, the evil biome cannot spread onto the snow biome, unless it gets onto contact to an ice block or just spawns on top of it. In Wynncraft, we see the corruption being majorly slowed by Theoricks ice, so it follows a similar concept to Terraria. Also, it seems that the corruption also has somewhat of a hard time going through the desert, so this is just proof Wynncraft is still pre-hardmode.
My second piece of evidence is the Silent Expanse. The expanse holds many fleshy and weird abominations reminiscent of the enemies that spawn in the corruption in Terraria. Also, the eye looks a lot like the Eye of Cthulhu.
My last piece of evidence is the decrepit sewers. The fact they used it as a jail and that skeletal enemies spawn there definitely makes it the dungeon from terraria. Even how the sewers is built makes it look very similar to the terraria dungeon

 

No.
The snow biome is one of the only biomes with a corrupted variant, along with the desert biome

 

Shame the jungle doesn't get the same treatment, and instead just becomes forest
