Narkvosu just wanted to survive.
At least long enough to complete his quest. He could care less about ever returning to his home city. Alone, he explored the last obstacle to his journey, an ancient cavern carved out long ago. Concrete and steel are now dust. Bedrock exposed. Nothing remained, the running creek, the moister and gangumoss making short work of what was once probably a vast urban habitation. If one could not define any of the telltale signatures of a past civilisation, the sub-level appeared just like a long natural cave.
