Talk:What does that little "S" icon mean in the wiki?

Various links throughout the wiki have a little "S" icon to the right of the link text. For example, the list of monsters in Misery's Peak includes several kinds of zombies, which don't have the icon, and ice spiders, Devourer cultists, etc. that do.
