Timeless Corruption
Players take the roles of individuals unmoored from history through interference with the timestream. As beings without a recognized past, they can manipulate time, avoid notice, and pass through solid objects, but risk vanishing from reality altogether. The game focuses on restoring each character’s lost past while dealing with the forces that seek to correct these temporal anomalies.
属性／ステータス制（STR、CON、PERなど）ダイス（主にd20）ポイント制（ポイントを割り振ってスキルや能力を得る）
