Summary
“Drink your tea before it gets cold.”
Albert blinked, glancing at the faint steam rising from his cup. He knew those words weren't just polite courtesy. They were Mycroft's way of showing displeasure, yet also care, veiled in stiff language. It reminded him of all the letters the man had sent him over the years, though he had never once written back. Mycroft was always like that. Never direct, but impossible to ignore.
When his world had collapsed. when he'd lost William in a tragedy that carved an eternal wound into his soul and Albert had withdrawn, severing all ties, blaming himself for everything. He locked himself away, not in walls of stone and iron, but in a dark inner prison built of regret and unanswered prayers.
Charlie had come like a small flicker of hope. As if some unseen hand refused to let him drown.

Mammon, once again, loses a bet with a witch and is sent to another dimension.

Mammon Oneshots by elkysakura

Summary
A collection of standalone oneshots centered around Mammon — the second-born, the scummy, the loyal, the forgotten hero. Each chapter dives into a different moment, a different "what if," or a hidden side of him: from the raw ache of unspoken love to the quiet warmth of found family. Sometimes he's the fool. Sometimes he's the backbone.
These are the stories he never got to tell.
Some even came from alternate universes.
