Well... if my last post is read from a certain point of view then the option is available. I shall do it! Edit: all ready to achieve pyrrhic victory!
Irony: Jacen uses some spell, rolls horrid perils of the warp, summons daemon-primarch fulgrim instead.
Turns out that was Jacen and Claudius' plan all along so they could kill 'Fulgrim' or 'Fulgrim's husk' as Lorgar would say.
I am so confused on sides good or bad but I know Cluadius violated the sacred by killing Alderson and attempting to kill a Company of another Chapter.
@Avenging-Angel Lol, you have no idea how badly Zuriel wants to join him and kill Claudius (@matt23 no offense dear battle brother ) But alas, he can't in good conscience abandon his duty (next character I'm making ain't gonna give a damn )
