Though the Dawngate may be no more. There are two projects that look to carry on what it was.
First, we have Project Aether Forged, that looks to create a new game in the same style of the game we loved. More info can be found on their subreddit https://www.reddit.com/r/aetherforged/.
Second, the Spiritgate looks to recreate the Dawngate completely in the Dota 2 custom games. Their subreddit can be found at https://www.reddit.com/r/spiritgate/.
