Illustration from chapter sixty five of '"Expedition to the Cloudbreak Islands":https://www.fimfiction.net/story/466115/expedition-to-the-cloudbreak-islands ', based on an online RP. The ponies push through the heart of the abandoned molekin mine, running the gaunlet of the central cavern, which holds the main spidrow nest. The old mine train is pushed to the limit as they tear across cavern, enduring a withering rain of magic and arrows from the arachind defenders. Set Sail and Reef Skimmer split off in a desperate rescue attempt while the others make a run for the Pyramid of Gnosym.
