Dark Iron

This metalic substance is found in deposits within the sediment and is mined to make items and tools of ghostly metal ectoplasm. It is hammered and shaped cold by ectoplasm workers. Ghostly fire doesn't harm it. Soulfire flame causes it the writhe and move away. It is said it is formed when the tears of gods burnt the soil and was carried in the Traces. It was formed by the ghosts of the first shapes which pooled and solidified in the sediment.
