Vanguard Dragon Slayers
The world of Tanara is a very dangerous one indeed. What was once the peaceful megacontinent Moga has had its lands ravaged, civilization crushed and nations toppled. 600 Years ago, a scourge swept the world, killing a great deal and crippling the rest. The humans were left persevering, and have been rebuilding since, with few major cities finally cropping up very sparsely. Large beasts roam the land, and still accost those who stray too far.
To fight against the constant threat of the monsters, the strongest of those surviving have banded together to create a national monster slaying guild known as the Vanguard Dragon Slayers. It is their duty to assist in the expansion of Humanity and to protect those who cannot protect themselves.
