Silver and the iron this body runs on sit too far apart on a battery. Touch blood, and the battery dumps.

+0.80 V. The blessed metal is a position on the series.
2 · Iron-sulphur
The drive’s [4Fe-4S] cluster sits near −0.44 V.

Blood and tissue close the cell. Intact skin does not.
4 · Short

The Archon rides the host's circulation. A short circuit is a total loss of power for the colony as well.
The is calibrated to one redox couple: the low-potential [4Fe-4S] ferredoxin cluster, whose midpoint sits near −0.44 volts in clostridial-type proteins. Silver sits at +0.80 volts. The potential difference is 1.24 volts — an enormous electrochemical gradient by biological standards. When silver ions enter the conducting medium of blood and tissue they form a galvanic couple with those iron-sulphur clusters. Electrons dump. The fuel cell shorts.
The second mechanism is oligodynamic poisoning: silver binds thiol and iron-sulphur cluster enzymes across the modified cytochrome chain and locks them. Local contact becomes systemic because the drive is distributed through every mitochondrion. This is undergraduate electrochemistry applied with prejudice. Not holiness. A metal sitting in the wrong place on the galvanic series. The inlay sits in the blood-channel, not on the flat. A brother-armourer in 1308 could not say why.
