Touring the Stars: Ionus provides us a report on a geologically old world with a dry atmosphere. Even at the beginning of the product, the in universe reports admit that this world isn't too interesting. However there is a history to this world, plus it isn't lost or dead like some of the other Touring the Stars releases. There's no strange animal wildlife, rather write ups on two vegetations which might be intresting from a fluff perspective for GMs.

This release's adventure seeds are interesting, incorporating things like breaching hulls and water filling up sections slowly each turn. So while the world itself might not be too interesting, the possible activities around it could be useful in crafting unique situations for some games. The world's existence is owed to being a secret shipyard after all, from a covert ops angle GMs might find that fun.

Compared to other Touring the Stars releases, it isn't horrible nor out of the ballpark excellent. It is a old world that is still active nestled within the Free World's League. There's potential for causing mayhem within a world slated to be a Warship production facility.
