Back to the topic of the thread (idk what all this DRS and whatnot talk is about), it really feels like, given the theme, the glow, and especially the fact that the glow colour of the final step of each of the Manderville weapons is identical (something that has not happened with any other relic), I cannot help but think they ran out of time designing the models for the final form, and just shipped the models that were intended to be the reward for the new Arcadion raid Savage. Compare, for example, the final forms of the Bozjan relics. PLD's yellow-white, WAR's red-orange, DRK's purple, GNB's blue. The theme is similar, with the 'teardrop' shapes for the glow, but the colour is different. By comparison, the Manderville weapons.

And as an additional point of comparison, how about the Asphodelos weapons? They, like the Manderville relics, share a consistent theme and colour scheme for the glow (white fantasy script, marble/stone looking weapons, any 'missing chunks' due to damage replaced/repaired by the glowing white 'letters')
