I'm going to guess that the virus can affect any creatures, but presumably not elders.

As much as I would like to say the snake-like monster to be a leviathan since its movements are closely related to that of the Agnakator, I'm going to say it's a new speices just because of how it looks.

1. scales are different from other leviathans.

2. only 2 limbs, most leviathans has 4.

3. It shows no similar movements to other leviathans other than Agnakator's sliding around.

4. Just far to different.

And lastly: in the last scene, is that another snake-like creature? or the same one from the beginning?
