Background / History

Li Weide arrives at Hogwarts with Tom Riddle after temporarily living in Hogsmeade Village. Before enrollment, he already possesses an extensive inheritance of Dark Arts books and demonstrates a habit of planning around magical surveillance, including purchasing secondhand wands to obscure his prior spellcasting. 42

He is an Ancient Magic user and becomes Senior Sister’s student in dream-based lessons. She teaches him both Nightmare Magic and the subtler application of Ancient Magic: reinforcing ordinary spells rather than visibly releasing Ancient Magic outright. 46 64

At Hogwarts, Li Weide quickly establishes himself as an exceptionally capable Slytherin student. His public duel with Tom and later victories over hostile pure-blood students make him a focal point for students facing discrimination within Slytherin. He turns this support network into the Mutual Aid Society. 90 91 100

Li Weide repeatedly expands his influence through research, mutual aid, training, and material support rather than promises alone. The Society later becomes part of the wider Hydra organization, with Tom serving as its “Head Trainer” for disadvantaged students. 389 418

After learning that his world faces a future demonic invasion, Li Weide concludes that gradual reform is insufficient. He resolves to consolidate global power, build armed forces and infrastructure, and assume the role of a Dark Lord if necessary to prepare the world for the coming calamity. 493 494 498

Personality

Li Weide is highly strategic, observant, and pragmatic. He routinely considers the benefits, risks, and leverage within a situation before acting, whether dealing with pure-blood prejudice, recruiting allies, concealing his magic, or planning research. 64 363 503

He pursues power openly, but rejects power that compromises his reason. He extracts Residue from himself rather than allow its negative emotions to influence him, regarding rational control as more important than raw strength. 378

Despite his manipulative tendencies, Li Weide is not purely self-serving. He increasingly recognizes that individual strength is insufficient and delegates responsibility, empowers companions, and builds organizations capable of acting without him. 389 514

His attitude toward others is often teasing, blunt, and occasionally inappropriate, particularly with Tom and Miravia. However, he places genuine value on communication, mutual support, and fulfilling the promises he makes to those who follow him. 450
