They're wraith that fill the vessel of Hassan. Each of them are not a heroic spirit by themself but they all qualified to be summoned to fill the vessel of Heroic Spirit Hassan-i-Sabbah.

the hypothesis are interesting but I don't think death as servant means the death of the wraith. The wraith are only called to fill the vessel of other heroic spirit and such once the vessel gone they might gone back to become a wraith, Kojirou is another wraith of similar type. now considering Hassan and Kojirou legend are way over 200 years ago and suppose that normal wraith lifespan cannot be longer than death ancestor Stanrobe Calhim which probably can still live until 22th Century... it might be the case that

1.) They're summoned across time, therefore they will be summonable even tho the wraith are no longer in this world. with this hypothesis it is possible that even if the wraith got destroyed the world can simply summon it from 0.1 sec earlier before it gone, or maybe from parallel world.

or

2.) They're special wraith that are not marked as anomaly for their relation with heroic spirit, as such it's possible for them to live indefinitely
