“Jungle of the Jade Jaguar” has enough content to run and the Sword system is interesting and thematically appropriate.
JJJ could definitely be expanded into a much larger adventure and the text “Magic pulses from this weapon, a cut straight into the dimension of THE GREEN – and from that cosmic wound pours an unending reservoir of life. Flora and fauna, ceaselessly evolving, spill forth in a riot of unchecked creation...” is an interesting enough premise that it could support a much lengthier module and bestiary - which i would like to see.
So as it is, it’s pretty good! And the skeleton it provides could be laden with a very weird body for an even more involved module.
