Hello Watcher!

A blog that I frequent about mythological monsters just posted a very interesting entry on an Irish monster called Cathach. https://abookofcreatures.com/2019/11/15/cathach/ Cathach herself is a very cool beast, but the article also mentions several other creatures that were supposedly present in Ireland during the story, namely Cathach's siblings Dabran and Farbagh, the "gatekeeper of Hell," the "all-devouring sow," and the "red demon of West Ireland." I was wondering if you were familiar with any of these creatures, and if so, what you could tell me about them. Thanks!
