* Outposts **do not** need to be fortified to earn ADA rewards
* Outposts can be fortified using derp character NFTs
* Anyone can fortify any outpost, even if they do not own it
* The outposts' faction determines which character collection can be used to fortify it
* All characters fortifying an outpost earn Derp Dollars(DD) each epoch
* A fully fortified outpost earns Derp Dollars each epoch
