Description
Tethra was a prominent Fomorian king, revered for his rule over Mag Mell, a mythical paradise often described as a realm of eternal youth, beauty, and joy. Unlike the grim underworlds of other mythologies, Mag Mell was a utopian haven, accessible only to a select few through death or glory. Tethra's association with this paradise elevated his status as a chthonic deity, embodying the mysteries of the Otherworld and the transition between life and death.
In the Second Battle of Mag Tuired, Tethra met his demise, but his legacy endured through his magical sword, Orna. This enchanted weapon was said to recount its deeds, serving as a testament to Tethra's prowess and his deep connection to the supernatural. His rule over Mag Mell and his role in the battle highlight his dual nature as both a warrior and a guide to the Otherworld.
Tethra's story reflects the Fomorians' complex portrayal in Irish mythology—not merely as antagonists but as integral forces within the cosmic balance. His character bridges the realms of chaos and paradise, making him a figure of both awe and reverence.
