I know nothing of this man, or his offspring, but I do know one thing:
The Sons will mourn for the lost.

The Iron Wardens mourn for you

''We know not why our paths did cross,
Only that too soon was it ended,
Only that it will be long before our hearts are mended,
I know that you will walk in the Halls of Heroes and Champions,
This world and here after will always be yours and mine,
Your name echoing in the lands of once upon a time.''

Only my respect and condolences for the family. No parent should bury their children.

May the God Emperor watch over them for the Emperor protects brother despite our differences may Chaos Undivided give you strength in these times

The lamentations of the Eldar join yours and may they find peace in the infinity circuits.

I am soon to be a father myself next month and this thread brought me to tears. You will be in my prayers tonight. I am very glad to see your Brothers rally around you in support.

I can think of no greater pain than the loss of a child my condolances and sympathies go out to you and your family Corvus.

Condolences!
No man should ever bury his children...

My greatest condolences and sympathies. Always remember they will be waiting for you by the Emperors side.

Not much else to say that has not been said, but ill take up the black with you..
