Hmmm, an interesting concept for a fantasy environment.
Ruins are a common theme in artworks like this, however, there is certainly many unique aspects that make this piece stand out. Not only do the autumn coloured trees give it an enchanting atmosphere but also the design of the lantern posts gives it a sense of freshness.
Not sure what the blue crystal warriors are meant to be since I'm not really familiar with Guild Wars 2, but I still find this deviation a truly magnificent work of art.
Splendid work, fellow deviant, and congratulations on the Daily Deviation!
Those blue warriors are ghosts cursed to haunt the land and fight any living creature they encounter. The last human king of this kingdom unleashed them to drive back his mortal enemies.
It is the lore of the game. I'm a long time GW2 player. Interestingly, there's no way to permanently defeat those ghosts; part of the curse is that they always come back, even if you defeat them.
I couldn't have said it better myself.
Abou the crystal warriors: They could be a final remnant of the opulence of the land's past rulers. (don't know anything about GW2 either)
Congrats on the DD.
