DDS and all other files you can put them right in the mods folder
I don't use subfolders for modded files.
The icon used i don't know from what spell it is . i just saw it there.Is order magic because i forgot to change the line that specifics the spell class in the file
spell.txt but you can decide what class to be by changing that line.
school=1 is order
school=2 is distortion
school=3 is chaos
The warrior model is the same model used by neutral hero Sir Amber but i reskinned him and used another pictures in interface_textures directory, takken from Hellgate London game.
