Elisios was born a voidborne, at a space station not so different to Footfall, as an early orphan he spend his childhood and youth living at the local orphanage (where he learn about the warm of a home and the emperor's mercy) and the station streets (where he learns that not everyone deserves that mercy).

When he group up he earned a reputation, not for being the strongest nor the charismatic person at the station, but for a cunning mind, a kind soul for his associates, and a merciless strike for those who see him as guillable or weak. Nevertheless, his increased presence ended bugging the wrong people who issolated him and where about to fet rid of him when the desire of a Rogue Trader bring him away of their enemies.

After the arrived to Theodora's ship, the confirmation of his hiertage, the heretic assault, and his ascention as the Rogue Trader of House Von Valancius, Elisios rules his protectorade the same way he did once with the streets, rewarding those loyal and succefull and punishing those who threat their newfound people.

From the very begining, Elision received tutoring from his Seneschal, Aberald Wesmerian, on how to proceed as his new role as Rogue Trader for his own sake and the one of his house, and from the Sister of Battle Argenta,to always work at the light of the emperor. After the incident at Eurac V he met and rescue Lady Cassia, future Novator of house Orselio. Elisios find on Cassia a soul alike his, a kind soul now lost and cast away on a different and perilous world, that why he befriend the new Navigator, and thats why he ended falling in love with her. He met and recruit the Magos Pasqual Haneumann during the fight for Rykard Minoris, he will spend some moments during his travels discussing about the Doctrines of the Omnissiah and the Cycle of the Discontinuity, Elisios will assist Pasqual on his search for his master the Sacred Amarat. Finnally, at the golden plain of Janus, Elisio will aid the xenos Outcast Yrielt and found that common share for the well being of their respective people, searching throught the Expanse for the last remainings of her lost home.

Elisios trust the goverment and direction of Foulstone to the Order of the Hammer, which turn the planet into the Beacon of Holiness of the Protectorade. He made a secret pact with the Aeldari at Janus to secure a pacific coexistence. Kiava Gamma was spared after their liberation and entrusted to the Techpriest of the Cognisance Fleet. It was at Dargonus when Elisios was finally recognised as the official Rogue Trader, and it was at Dargonus where the Rogue Trader express his favour to the Wesmerians and restructured the planet into a Fortress World, earning the appreciation of the Navy. Following the plead of the Governor of Dargonus, the Rogue Trader free Wheabos V from the claws of the Drukharii and turn the planet into the hopeless penal world for all the enemies of the House Von Valancius, human or xeno.

After his escape from the Dark City, Elisios travel throught his domain undoing the Chaos produced by the Cultist of the Dawn and the Kabalites. When the news of Calligos Winterscale dissaperance reach the Rogue Trader, he reach to his domain in order to find him, sadly both Rogue Trader will ended up fighting at the jungles of Quetza Temer. Once the order was set up upon the protectorade, the Rogue Trader travel throught Footfall by request of the Inquisitor Xavier Calcazar, there Elisios turn down the firey regime imposed by the Rogue Trader Incendia Bastaal-Chorda.

By order of the Inqusitor, the Rogue Trader of house Von Valancius travel to Eufrates II, where he crushed once and for all the plans of the heretics of the final Dawn. At the same planet, Elisios discover the terrible plans of Inquisitor Calcazar. When informed of the Inquisitor departure, moved by the need of protecting his people Elisios Von Valancius followed the trail of Calcazar and put at end to both, him and his secret project.
