A comment attack ! Yaaay ^ ^ Welcome back, my friend :D

Citizens indeed posses advanced self-customization abilities, via the individualized "Selforge Citizen Essence" they are symbiotically bonded with on a metaphysical level (imagine an imperceptible/featureless 3D 'shadow' occupying the same space as them).

Their SCE are actually  engineered pieces of Lawrence's own soul, whose bonding with allows him to share his abilities with citizens (notably self-customization), so their primary abilities are actually his own, permanently shared with them through this symbiotic bond.

The extend of said abilities remain limited though, for societal and balance-related reasons.

The main difference between them is that Citizens are originally normal entities, whose being was "expanded" with an additional "dimension" that is their Citizen Essence, which memorizes their personal data and applies desired changes in real time. For example, they think "I want to teleport there", the thought is memorized alongside their general data, and their SCE answers it by teleporting them to the chosen destination (flexible programming).

The Silver Sisters are the opposite : while Citizens are physical beings with an extra non-physical dimension, Sisters are non-physical beings with an extra physical dimension. They were born from slivers of Selforge Essence (Lawrence's being) that he fully autonomized, withdrew all consciousness from and imprinted with their own personality, Sisters existing physically by materializing bodies for themselves (the 'shadow' creating/inhabiting them).

So you could say that Silver Sisters are Lawrence's spiritual daughters (although they are conceived through his Materium physiology rather than created to anchor their physicality / humanity) while Selforge Citizens are his adoptive/biological ones (although genetics don't mean much in Selforge City since citizens' DNA changes every time they self-customize).
