Chief Librarian cameo

I have heard that there is another possible story in the works, either for this game or the next one. If the new story continues with Titus, perhaps we could meet another legend among the Ultramarines, now that we have met the Chapter Master?

Varro Tigurius is one of the most powerful psykers in the Imperium, and is vital to the Ultramarines, as his future vision has allowed Ultramar to avoid many dangers thanks to his timely warnings and the decisions made by Calgar thanks to his advice.

Many fans of this chapter were happy to see Marneus Calgar. And while we know for sure that Roboute Guilliman is too busy with his own things, Tigurius aiding Titus seems to be something very likely to happen.
