And the results are?

Hector King, a man in his 50s, no family or friends to speak of, paralysed from the waist down due to a work-related accident. Now he lived alone with his pup Huskey.But one day, he mistakenly summoned Satan.“Ah, it's been a long time since I was summoned. You found my book? Good, what do you want? Riches? Women? Fame? Strength? Or perhaps, your legs? All at the discounted price of your... soul.” Satan offered.Hector, however, didn't need any of that. And so, his answer even shocked Satan, making that smug look disappear. “I... I want you to be my friend.”And from there, the friendship that would last eternity started, all at the price of Hector's soul....Year 2021,As a mortal, Hector died. But Satan decided to do something crazy, “F*CK IT! You're my best friend, I can't let you die. Hector, I am appointing you as Hell's Inquisitor, a position only under me.”...1935, EarthHector found himself in his old original physical body again, but he was now taller and buff.“I-I got a new last name? Hmm, it has a nice ring to it.” He muttered.He was, from then on, Hector King Washington.“WOOF!”And the good boy Moony was also there, bigger, buffed and more beautiful.
