~Oriel gave Sinbad two choices: Kill the Promen or take them from the planet to maintain the secrecy of their faked deaths. Sinbad chose to take them from the planet to save their lives.
~They were reunited with their long lost cultural progenitors, providers of the Promethean cult, the Salamander Chapter. They fulfilled their 10000 year old prophecy by returning three Great Crusade era relics. As a reward the Salamanders intend to take those who followed Sinbad to the homeworld of their Primarch.
