Connection between Havel and Stray Demon may be more than rock puns. In DkS1, Havel was locked in the Tower between Darkroot Basin and Undead Burg. The key from the Divine blacksmith has an interesting description saying he was locked in for good or bad. In Anor Londo there's a hidden room with Havels gear and a "Occult" Club. Something he wouldn't have as a loyal follower, suggesting he at least partly knew the truth of the gods/fire. I'm kinda shocked I don't see people mentioning this more often. Anyways, the Stray Demon gaurded his route as well but was stuck there. Dunno if this was intentional but at the very least a Chaos Demon that wasn't a Winged one was serving Lothric castle, trapped there. I haven't gone searching for more info on him yet but that's at least one solid connection. Thanks for reading.
