From the back cover:
"Fish for Breakfast is a Lejendary Adventure game scenario for 3-6 beginning Avatars. One or more Dwarfs (or Gnomes) in the party will prove useful, but these characters are certainly not essential. Abilities that may prove advantageous include Arcana, Enchantment, Hunt, Learning, Ranging, and Scrutiny.
The adventure is intended for use with the Lejendary Adventure Game Essentials Boxed Set. Where material from other sources is referenced, it is duplicated or paraphrased within the text. The Chronicles of Lejendary Earth World Setting - Gazetteer and Noble Kings and Dark Lands are also referenced, but are not essential for play."
