All in all i like this one. Its instesting starting settings, have flow in story telling. if only it have there where 2-3 more chapter then reviewing it as 3 or 3,5 wouldt be hard. as it is now there just not enough content do make better Judgement About It. As for Unique wording I would definitely Keep it as it is now. Its a Strength. and about thous writing mistake to quat my old english teacher "just keep writing and repeating, you will get the small things to right places in Time."
Shameless me rating my own work as the best, but what can I say? I want to try and be a good writer and be a good king of Goblins. I will not ask for money like others, but it you give it good rates and power stones u will me very happy and you will motivate me to write more. And on other hand u can insult me so I don't write more. I let that at your wishes.
