"Warrior of a hundred worlds. Mercenary captain of the Blood Wars. Sword of celestial vengeance. The planar champion moves between the planes, always driven to battle. She may be driven by a quest for justice or a thirst for blood, but she is feared throughout the known universes for her prowess."Imagine a Time Master but for alternate realities and multiverses. You get someone with the ultimate sense of Walking the Earth, But Now I Must Go, and even The Homeward Journey where the person's wanderlust or adventurous nature doesn't just take them across the world but beyond and between worlds. There is an increased impressiveness when a hero's traits are adapted for not just one grand frontier, but billions of them.
