Are there no other brothers that will see this heresy, and turn against him before he turns them over to the traitorous side?

Perhaps smaug....everyone else has sworn loyalty to valrak above all else

Then they will considered traitors to the cause and shall be executed.

I cannot do it alone, but i will try.
The bastards of vigila mortalis will be in ruins

Call upon your brothers and let them know of the traitors and their plot among the enemy. Do not let them suffer the same fate if Valrak begins to whisper in their ears too

There is only one problem...
I have few battle brothers

When it will come to stopping Valrak from his False crusade the Brothers of the Emperor will unite to stop him

Why do you help me? Why do you help us?
