The contract sounds the most logical, just gotta figure out how to pull it off

There is a trade off when making a contract with a loa, so it works well with the story. They can mount/possess followers. They're given offerings. You got this. There are other loa that I think would be easier to write with because of more inherent/focused strengths and weaknesses; Baron Samedi who talks to the dead or one of the ghedes, but Legba could give you information as well. I might just be biased because I favor the Baron Samedi and his crew.
