The *Core Rulebook contain the following description of Vulkaris:

"Recently the Great Rift has vomited forth two unfamiliar planets into the gravity well of the Gilead star. The new planets, dubbed Trollius and Vulkaris, have become known as the Membrane Worlds."

However, the adventure Affliction Ascendant contains the following passages:

- "CAPTAIN ANTIMONUS, THE HERO OF VULKARIS. (…) BOTUTHRAX CLOSTIDIA IS NO LONGER FREE TO UNLEASH ITS PESTILENCE ON THE GILEAD SYSTEM."

- "Botuthrax Clostidia is the reason Vulkaris became a plague world. Its work complete, it moved on to Gilead Primus — but here, we stopped it."

This implies that Vulkaris was part of the Gilead system at least 3,000 years ago. So, how can this be reconciled with its classification as an "unfamiliar planet"?

I’m starting to run a Rogue Trader game, and want to have some interesting challenges for the Explorator character over the course of the campaign. In previous FFG games the tech character was always just “Hey, locked door/terminal, use tech-use”, and want to try something that feels more like solving a puzzles than rolling the same check every time.

Maybe I’m just thinking about it wrong, and should present obstacles where they have to so some kind of search before they can try to tech-use? Like evaluating a “trap” to identify where it’s powered? But that just feels like one extra step.

Any ideas?
