Aldronde
Aldronde, the Deep Sea, the Eastern Sea, or Aldronde the Deepest, is a vast sea of Nīmlad to the east of Rhusagos and Patrinor. Little is known about what lies beyond or within it, save for the distant Fire Islands.
Its winds are cold and harsh. They buffet Garnatos regularly, and stir up the waters of the deadly Gurmindār pass.
Etymology
Aldronde is Classical Paternic for “deepest (entity)“. It is the superlative form of the word aldor (“high, deep”), which is being used in this case as a substantive adjective.
