There must have been a time, long past, when animals much like apes looked up into the night sky and wondered about the stars: what those pinpoints of light were, and what they were for. Only a brief while after that, the apelike things acquired language; then stories began to be told, and fantasies woven about the stars overhead. That cluster resembled a hunter and, high above, the outlines of a great bear could be discerned. Such stories, told in the Pleistoђcene dark, kept the bogeyman away.
Animals have no interest in stars.

This brings up the question of how we define the time intervals we measure. What is a day? What is a year? The earth is in motion. Actually, several different motions all at once. The top-like rotation of the earth on its axis is how we define the day. The revolution of the earth around the sun is how we define the year.

Try It Yourself. Role Playing Games - Free Multiplayer Online Games. Aura Kingdom (AK) is an anime-inspired fantasy MMO from Aeria Games, boasting eight classes (plus one mystery class), a well-developed companion system and a unique skill tree. The game features beautiful, cartoony graphics in an open world with instances (dungeons) supplementing it as well. Players get acquainted with the game mechanics by doing a tutorial with end-game items and stats, but upon waking up start off with the usual sort of quest chain, which can be done quickly with auto-path. Leveling is fast; assiduous players can hit the level cap in a matter of weeks, if not days. PvP and crafting opens up quite late. AK features immersive combat with the player being able to dodge enemy skill-shots and run around the enemy while attacking. Overall, Aura Kingdom seems to be a well-polished even if not terribly unique title.
