Senterra is a plane of magic that is composed of two realms; the physical realm, and the Spirit realm. There are currently only two continents know to civilisation; Valoran and Sein. The known world boasts several bodies of large water currently known as the 18 seas and 2 Oceans with several islands and archipelagos populating them. The planet revolves around a star and has a single moon. Senterra's sun and moon have mirrored equivalents in the spirit realm.
Centuries ago, magical artifacts called the 'World Runes' were rediscovered. Over the following decades, knowledge of the Runes began to spread as more were unearthed. The world's brightest minds studied the ancient glyphs, attempting to determine the powers they possessed. Few could even begin to understand the importance of their origins, or the sheer power held within them. Some surmised that the Runes were integral to the creation of Senterra itself. The first use of these mysterious artifacts proved catastrophic, as they reshaped the landscape of entire nations. Mistrust quickly grew as those who knew of the Runes imagined such “Makers' Might” being used as a weapon. Conflicts related to these magical artifacts began to occur, known as the Rune Wars.
