Human-San'Shyuum alliance

The Human-San'Shyuum alliance was an alliance between the two species during the reign of the Forerunners.
== History ==
Even before they united their military and scientific strength against the Forerunners, the Ancient Humans and San'Shyuum regularly traded produce, items, and technology with each other. One such example is the Pheru, an animal domesticated and used as a pet.Halo: Cryptum Page 269
=== Human-Flood war ===
The San'Shyuum, like the humans, had used the powder on the Pheru to make them more "exotic," with an active black market in them. When the Pheru became aggressive due to the "infection," they killed their favorite pets, much to their dismay.Halo: Cryptum Page 273
Although San'Shyuum were infected by the "plague" during the Human-Flood war,Halo: Cryptum Page 270 it is apparent that they were not as weakened by it as the humans were, since they did not need any uninfected worlds like the humans did.
=== Human-Forerunner war ===
During the Human-Forerunner war the humans were already fighting Forerunners when they allied themselves with the San'Shyuum, combining their technology, weapons, and knowledge. It was this alliance that made humans formidable opponents for the Forerunners, inflicting many casualties on them.Halo: Cryptum Page 112 Despite both species being incredibly powerful, humanity was already weakened fighting a war with the Flood.Halo: Cryptum Page 272 Eventually, the alliance was destroyed in the Battle of Charum Hakkor, with human resistance completely crushed and the San'Shyuum finally surrendering.Halo: Cryptum Page 111
The humans, being cruel and fighting to last man, were devolved (rather than executed to extinction), with The Librarian being the only reason for their survival. The San'Shyuum, more willing to accept defeat,Halo: Cryptum Page 134 were quarantined to their native system. For obvious reasons, it was forbidden for the the remaining fragments left of humanity) to ever meet the San'Shyuum.Halo: Cryptum Page 172
