Mi Go

The Mi Go are an extraterrestrial race resembling a cross between crustaceans and fungi. They are not competing with the player, they have their own bizarre motivation but if the players plays their game he may be able to leverage them to his advantage.

Mi-Go perform two interesting actions in the world, one is that they launch Expeditions to recover very particular artefacts that concern them from the Age of Damnation and the other is that they grow "Fascinated" with interesting people - if their fascination grows strong enough they may begin to talk with that person, and eventually offer to take them on a fantastic journey in a brain-jar.... say no long enough and they may just go from asking to demanding. Most notables will not return from that journey, but those that do may gain unique abilities and knowledge (or be insane).

The player can attempt to manipulate who the Mi-Go are interested in, and the Old One can even volunteer to go themselves. It is important to remain careful however, because dealing too much with the Mi-Go raises a player's own fascination and they may decide to abscond with an Agent's very necessary brain.

The Mi-Go also have a unique minion the player can recruit if he has a high enough Arcana, the Mi-Go Attendant does not count as a minion and also cannot be dismissed. While it costs you nothing it increases your Fascination over time, leading to the aforementioned brain-napping.

Getting in Contact
Stumbling across a Mi-Go expedition will also allow the player to interact with it as a modifier and take different actions.

There is also an item which allows the player to make contact with the Mi Go.
