Who is Messmer's father?

[Jake]

I didnt get it

[DSANIC]

probably radagon... from even before godfrey

[Weedsmell]

he has red hair so was he born after the giant war? (i think they also mention the fellgod on his items)
i dunno i haven't done my homework yet with the dlc lore.... sorry

[Knavenformed]

With the red hair he should be an Empyrean child of Radagon and Marika since he continues the work his mother set out for him

[Quandangle Jones & JimJams]

I don't think theres any stated timeline of the wars so messmer could have been born after Radagon's recall and marriage then sent back to the shadow realm on his crusade.
