NISO

Okay...
I
Alex,
Arandor,
Vissy (Vissy?!! I thought it was Lock),
Heroist,
Kosha,
Lock,
Ment (well, it's obvious even without a caption - a hat and a beard - that's Ment)),
Nebo,
Ney,
Ples (and I thought Revant was depicted twice),
Revant,
Sezam,
Siv (but where's the rapier? :) ),
Amko, no, that's Shaman.
II
Emmm, Lock, or something?
??? I have no idea who that tattooed guy is. Based on his hair color, I can guess it's Nebo.

And where are the pictures, actually? :(
Okay, they didn't load the first time.
Very cool, I recognized everyone. Except for the person in the background with the Eiffel Tower.

Wow! Kosha looks great.
I didn't recognize everyone in the first picture. Where did we get so many winged characters? The first one is Vis, the third is Master. And who is the fairy? Kosha? Kosha. And who is the fourth winged character? And Ment looks cool)).
I recognized everyone in the second one, although it took me a moment to recognize Siv.
In the fourth one (with the mermaids), I'm not sure if I correctly identified Heroist.

The simplest thing would be to just use thumbnails.

That's actually a good idea.
Unfortunately, not everyone has a fast internet connection. Now I have to wait for all of this to load ((

suddenly, it turned out that half of the pictures didn't load for me at all. Great internet, I guess.
