Rise of Dragonian Era (RODE) sunset this past November 13th.
In a shutdown notice on the game's now-defunct Facebook page, the studio posted, "RODE services will close permanently. We apologize for this unfortunate event. But we look forward to seeing our RODE players a part of our Netgame community again in the future."
RODE launched in early 2012 and featured a permanent dragon companion and aerial combat as its main selling points.
