7 Sky: Fang of the Wasteland. LitRPG.

"Elegant magic is powerless when glowing granite falls from the sky." How do you stop a world war when you are a despised half-blood with ten copper coins in your pocket? The world of the Floating Islands, suspended above the boiling lava of the Fiery Abyss, is ready to plummet into the void. While proud elven lords on snow-white frigates prepare to burn the lands of starving orcs, faceless beasts lurk in the shadows of the capitals, weaving conspiracies and yearning for the end of the world. Grak refuses to be a pawn in someone else's game. On the ruins of a dead island, he raises the Bastion—a Free Port and an impregnable fortress for those who have nothing left to lose. His army consists of rogue mages, thieves, leprechauns, and mad goblin engineers. His fleet is a ragtag armada of overloaded galleons and patched-up sloops. Standing against them is the flawless, magical Armada of the Silverwood. But when the heavens are ready to fall, the elegant magic of Light will clash with crude orcish steel, toxic alchemy, and the absolute ruthlessness of outcasts.
