Havero

The Havero was a titanic beast that cut its way into our universe, only to get snagged on the dimensional tear it made, and stranded out beyond the shore of Reloria

While far out, it still proved to be a blight on the townsfolk of Lanerus. Winged daemons poured in from its tear in reality, and it would occasionally writhe its tentacles all the way into town. It also blocked incoming trade to the island, effectively putting the Lanerian economy to a standstill. With such a looming threat in the distance, the citizens had no other choice than to spark efforts to kill the beast.

Appearance
The Havero was well beyond colossal size, bigger than our previous understanding of size limitations of living beings. One of its tentacles alone stood colossal sized, with the difficulty to match. What we saw has also been theorized by some to only have been part of the total creature, as we don't know how much of it came through the portal before getting snagged.

It was semi-amorphous mass, hundreds of writhing black tentacles, jutted out from its oily gooey body. While difficult to look at for mentally unprepared folk, if one studied it, they could see what counts as "facial features" in the center of its mass. Several milky white eyes, like filled pus sacs, sat atop multiple stretching maws.

Truly, a terrifying sight to behold.

The Rift
When the Havero first tore its way through dimensions, gigantic arcane runes known as "rift stabilizers" appeared along the Leylines of Reloria. Upon discovery, their purposes wasn't theorized until a few weeks after, that they acted as anchors binding the rift to reality. From that point, they were targeted for destruction to destabilize the portal, and heal the dimensional tear with the Havero trapped inside.

What exactly lied beyond the rift is still up for debate by scholars today.
