The relationship between Harmony and the Trellium spikes has been confusing me. The below is my understanding, not an attempt to declare truth and I hope someone can point me to a WoB or book reference that will correct whatever I'm getting wrong.
Hemalurgy is Ruin's investiture system. One characteristic of Hemalurgy is that Ruin (and thus Harmony) can see and influence, to some degree, anyone who has a Hemalurgic spike. The Trellium spikes we see are created through Hemalurgy, and therefore should follow the rules of Hemalurgy and make someone spiked with them open to Ruin/Harmony. So since this is not true, does that mean Hemalurgy is not entirely of Ruin? I get that Trellium is a god metal, but why should that break a rule of an Investiture system? Do we have any other examples like this?
Thanks friends!
