Interstellar Otherworld Architect

In an interstellar age filled with civilizations of every level, a holographic game appeared out of nowhere and won widespread acclaim for its unprecedented realism. But no one expected that this game would give rise to a world-changing technology: the creation of otherworlds. By salvaging fragments of worlds from the void and using them to build miniature otherworlds, people gave countless ordinary citizens across the stars a chance to benefit, even those with no talent and no way to gain great power. They could enter these otherworlds and search for the rules hidden within them. After clearing a world, they would obtain a card formed from that world, allowing them to become the most unpredictable Spellcard Masters in the stars. Those capable of creating otherworlds came to be known as Otherworld Architects.
