Concept: “Expanding on a snippet of lore from the Mörk Borg core rules, Anthelia's Black Glass is about examining the notion of "monster" in a world of anti-heroes.”
Content: Those who fight monsters are doomed to become them
Writing: Descriptive text is well written and evocative with an extremely efficient stat block
Art/design: Illustration makes good use of the fragmented reflection conceit; the text is printed backward—you have to read it in a mirror
Usability: Easy to use without consulting the document at the table; includes a non-mirrored version, but that defeats the concept and execution

Concept: “A bestiary brimmed with 105 pages, 42+ Occult monsters, including Esoteric scriptures to die for, and Hopeless dungeons to die even more for.”
Content: Monsters and scriptures and dungeons, Oh my!
Writing: Text ranges from bloviated to concise; brisk to simple. But it is reliably miserable.
Art/design: A menagerie of styles as creative and varied as the community which spawned them.
Usability: Divided in three sections with a full index to aid navigation. Entries of varied accessibility and ease of reference at your table. 

Concept: “What happens when the lore of our world collides with the Dying World of MÖRK BORG?”
Content: The first volume of collected FÖLK-LORE Jam entries
Writing: Varies by author, see individual entries under the FÖLK-LORE Jam tag
Art/design: Varies by entry; single-page entries are well balanced in spreads
Usability: Varies by entry, but it’s all Mörk Borg—how tough could it be?

Concept: “Have you fvckers got my eggs?”
Content: A crazed, skin-suit wearing axe murderer
Writing: All mechanics, with a table of curses for whoever kills hem
Art/design: Putrid, visceral graphics in line with the concept
Usability: Escalating attack damage will require a bit more attention from GMs; small script may be challenging to read in print
