Long story short: I left WoW during Shadowlands and returned recently, but I do more Legion content than Dragonflight content, so I noticed some things changed in Legion Dalaran since the last time.
And one thing I noticed is this guy:
A Tauren Paladin next to a basket of cheese. I googled it and so far I’ve found no information on why they added this NPC to Legion Dalaran.
All that I know is that he was added in Dragonflight patch 10.0.
Is it a reference to something? A tribute to someone? Part of some sort of cheese related World Event or Secret?
Nobody seems to know.
The mystery of Sunwalker Cheeso is yet to be solved.
