Yasha has some delusions from his childhood on Euphora, but his affinity for technical matters brought him to the attention of the Adeptus Mechanicus. p. Born on the death world made him a bit crazy. Might have one sister left. Spent youth scavenging parts. Eventually got press ganged onto a Navy ship. Ended up helping the Tech Priests out with something and got adopted into the Adeptus Mechanicus. Spent decades working with them. Always seen as a little bit off. After a while, the Machine God told him that there was some specific piece of knowledge out there that he must go find. No details, but finding it is necessary for the good of all. Took aside his Magos and told him of what he has to do. The Magos told him he could join the Explorators, and there was a convenient ship nearby.
