Aye i would like to see another side to Guilliman. We've seen alot of Dorn, Horus(obviously) Magnus, Russ(or will do) Fulgrim, Mortation, Ferrus, Sanguinius, Angron, Lorgar(well again will do soon) Alpharius, The Lion and a little bit of Corax. Still need to flesh out the others though. Khan, Vulkan and Pertuabo haven't even bee touched really and haven't had any books confirmed for them at all, although i think Perturabo might be getting some limelight in Age of Darkness. We already know a little about Curze from the Night Haunter books. Guilliman will obviously get a book though, be interesting to see how they portray him.
- What's going to happen to Aximand.
- How will Loken and possibly Tarvitz and co. escape Istvaan, and what will happen to them.
- What will become of Garro, Qruze et all.
- Will the Alpha Legion twist the plot around a little more.
