After a Long and Perilous course of... Spikes, Infected bugs, And Floating Infected Globs, You decide to take a rest At a Calm spot... which had the corpse of a vessel.

You Rested There for awhile...

Till the Corpse moved.

A Blob of infection Rose from the top of its Mask...

You readied your Nail/Needle (Depends on what you're wielding, Really.)...

Huh. Weird.

It's not fighting...?

It just stood there, seemingly analyzing you.
