This supplement provides exactly what the description suggests - 21 pre-generated characters of various races, classes, levels, and alignments. Each character fits on a single neatly organized page. The format is quite plain, but well organized. These are simple boxes and matrices that clearly detail the character's attributes, spells, bonuses, and equipment. A lack of ornamentation means it won't tax your printer heavily. The equipment included is both magical and mundane with the arcane ones being highlighted in bold font. The magic items are not too numerous nor too powerful and are typically quite practical. For better or worse, there are no character descriptions included. These characters scan easily be dropped into any existing campaign on short notice.
My only complaint would be a minor one - there is no table of contents included. I would have liked to see a table which detailed the race, class, and level of each. If a ToC is included then it's not being displayed in my pdf viewer of choice.
