After replaying demons' souls a month ago. And recently buying ds2:softs. I just noticed how Veldstadt's armor set is just a recolored Dark Silver set.
Not only is the armor set nearly identical to the Dark silver set, the weapon it's paired with is also similar to the Bramd (Aka the Grant in ds1 and morne's greathammer in ds3 due to the fact that they are all identical in shape but also have Wrath of the gods built in) used by Garl Vinland of demons souls
Tl;Dr I think the Veldstadt's set and Weapon are references to Garl Vindland's Dark Silver set and Bramd
