Song of Sadness
Treggonarean is a draconic king who makes lair deep in The Beastlands outer plane. According to Arvius, he is fabled to possess an Orb of Dragonkind.
From Salazar’s legend lore:
Treggonarean is a half-dragon ruler who has reigned for centuries in the Beastlands. He ruled through fear over a large population of kobolds, who have grown larger and stronger in the Beastlands than your average kobold.
Treggonarean has coexisted with many local dragons, including an alliance with the great red dragon, Garrengik, and her two children.
