Shadow of the Serpent
Lieutenant-General Gustavo Trost is the commanding officer of the 58th Vostroyan Firstborn Regiment. A proud, Emperor-fearing man, and a true example of what it means to be an Imperial Guardsman. He tends to lead from the front, much to his attendee’s dismay, but it inspires his troops to the point of fanaticism. The Ecclisiarchy would be proud.
He always sees help as a two-way street. If he receives assistance, he will go out of his way to return the favour; be it for Space Marines or even Xenos (although the latter he is a bit reluctant to help).
