Siderius sprinkled a thick layer of salt beneath each of the victim's beds. He then connected them together via thin sulfur lines.
Looking from above, the seal consisted of five different circles of white salt interconnected with each other with yellow powder of sulfur.
Salt to ward off evil and Sulfur as the gateway to their souls. The combination of the two shall open the pathway inside their eyes, allowing the souls to be freed.
'It would be better if I have some mercury right now', Siderius thought to himself. His Mercury reserve had run dry for quite awhile now.

But Siderius had to make due with what he had. Like he always did since he had come to this world.
