This edition of the XPS concentrates on Turjan-level material. To wit, these snippets from the editorial:
"In this edition, aimed to support those who wish to experience the darker side of the Dying Earth we concentrate on Turjan-level material."
"As mentioned, shrewd observers will note that there is a distinctly Turjanic feel to this issue of The Excellent Prismatic Spray. The articles have a darker feel, the scenarios are more dangerous and for more powerful protagonists. [A]t this level the essential elements are an opportunity for bloodshed and a sense of horror as one searches ruined wonders for lost knowledge. And now your characters can have long term aims, objectives worth following."
