Wow, that looks like a cool event. To be honest, I'm not very into cosplay. So probably wouldn't join in. But it is fun watching people enjoy themselves. You got some great photos of the event. Seeing the weapons and armor would be fun. I have no interest in owning such things, but watching the craftsmanship is always very interesting.
Do they do these fairs often there?
I have no idea how often they were held and only heard about this one by accident. I presume it's held annually although I think the individual groups hold their wn events on a regular basis.
