Temple of the Iron Ascent

In the shadow of long-forgotten mountains lies the Temple of the Iron Ascent, an enigmatic complex that spirals upwards, carved into the heart of a sheer cliff face. This ancient structure was dedicated to Thakron, the Forge-God of an enigmatic civilization known for their mastery of elemental metalwork and alchemical wonders. Travelers tell of the temple's historical significance as a repository of knowledge, lost artifacts, and powerful constructs bound by the very essence of the raw earth. The structure is said to house not only guardians created from noble metals but also remnants of trials once devised to test the worthiness of those who dare seek the blessings hidden within. Adventurers who enter may find glory—and peril—beyond imagination.
