HeroesLAND is another “online heroes” game.

It is not uncommon for a Spearman to dream of becoming an Angel, a Fiend to become a Devil, and a Basilisk to become a Wyvern or even a Hydra, but not all of them succeed. However, there is one day of the year when, among other things, it is permissible to try on other guises. In the mundane "real" worlds, this day falls on April Fool's Day.
However, the gods also like to joke, which means that any transformations are possible, including reverse ones. In addition, on this day, other amusing pranks sometimes occur.
