After Guilliman was captured by the blacksteel lord, all members of the cohort gathered their strength using their new found influence from the gate incident and tried to free him.
But time and time again, they failed. Victoria and Jemie even resorted to sneaking into the blacksteel mansion and were caught by the blacksteel lord.
As a result the cohort was collectively pressured by all the people they knew to stop trying. They placed them under constant surveillance and monitoring for months until.
On a particular day, a letter arrived in the Blacksteel mansion directed at the lord itself.
It read
"

The burden of losing one of our own had blinded us for the longest time but thanks to you we understand that it's time to move past that and handle the threat at hand.
