Brotherhood of the Yellow Sign.

[dayglo-sword]

Any country where Hastur is accepted should be hostile to Mi-Go experiments. (rivalry from 'The Whisperer in Darkness')
Need some form of jeopardy for the body-transplant player if in such a country.
If Imperial America exists possible open hostility against the swapping player.

[dayglo-sword]

Initial warning event added. Needs follow-up events with risk of discovery by the Brotherhood.
Brotherhood can exist after the publication of the King in Yellow but before IAM.

• If the player is IAM - any divergence from absolute monarchy or loosening of Issues should act as a trigger event for possible discovery.
• If the player in full cultist country - have a visit by the brotherhood as an event leading to possible discovery and hostility from IAM.
• Else the player should be safe but warning of Brotherhood activity given.
