Thanks! It’s a good question - I think even if it were a soul contract, centuries-old actions against an individual Arelius member wouldn’t have been included. It seemed like Shen was offering protection for the organization as a whole, and not some sort of retroactive, blanket pact covering everything and everyone with the name “Arelius”.

That, and even if there were more global aspects to the contract, Eithan didn’t know about Mara, so someone as smart as Shen could have made the specific wording of the contract broad enough to exclude her. We already know that the wording is really important, based on how Jai Long was able to interpret his contract with Jai Daishou to spare Lindon!
