Furnace Core

The Furnace Core is a giant stone spiral stairway, that serves as a passage between the Underworld and Overworld on Jarilo-VI. People used to travel up and down on it freely, but then it was sealed, with only Geomarrow and other goods allowed for automatic transport. However, Sampo somehow is able to travel freely through it. 
After Cocolia sealed traffic, Svarog set up encampment there to prevent Underworlders from heading up and to protect them from the Overworld threats.
