Reincarnated into the muddy guts of a cursed swamp as a tsetse fly, former office worker and master-level cynic Buzz Windbreaker quickly discovers that survival is both absurd and magnificent. The air is thick with poison, the predators are many-limbed and spell-woven, and the prey? Just as desperate as he is.Yet with every drop of blood he drains from beast, beastkin, or unlucky mortal, Buzz unlocks fragments of an ancient arcane lattice that spirals beneath the skin of the world itself—a system of runes, incantation spirals, and primordial energy flows forgotten by even the highborn mages.His evolution isn't just physical: it is architectural. Each new form is built like a spell—symmetrical, efficient, cruel. Wings shimmer with sigil arrays. Proboscises become siphons of mana and memory. Legs are sharpened to runic blades. Jokes sting. Death stings harder.Soon, Buzz isn't just hunting. He is ascending.

Resurrection of spiritual energy, faith first.
