Takenuma Swamp was a festering pit of dishonor, home to all sorts of depraved beings. Ochimusha, samurai who dishonored themselves through selfishness or cowardice, often had nowhere to go but Takenuma. The rat-like nezumi supported themselves through dark magic, mercenary work, or theft. But the darkest of Takenuma’s inhabitants were its ogres. Unlike the rest of Kamigawa, who had mostly abandoned the kami since the war started, the ogres still worship the oni, twisted demon kami who controlled forces like evil and death. Wherever ogres walked, blood flowed freely as they strove to satisfy the hideous whims of their oni masters.

Takenuma name means "bamboo mire".

"A wanderer has told me of an assassin in the Takenuma Swamp who uses her dark arts to animate her enemies' shadows against them. A wild tale, but it explains much." -Diary of Azusa (Kiku, Night's Flower)

"I prefer to weave my magic through oni blood, but yours will do in a pinch." (Takenuma Bleeder)

"The wizards of Takenuma Swamp faced the horrors of humanity every day. It's no wonder they fared so well against the kami." -Observations of the Kami War (Psychic Spear)

Knowing Takenuma Swamp to be dangerous, Hisata set wards to warn him of predators. He never imagined that his murderer would pass through them unhindered. (Bog Wraith)

Takenuma was filled with a chorus of moans, shrieks, and wails. Some came from the living, some from the dying, and some, most horribly, from the dead. (Death Denied)

"We are recalling all forces from the Takenuma Swamp. We lose men daily to kami attacks, and it seems our defeats only encourage them further." -General Takeno, letter to Lord Konda (Swallowing Plague)

After their worship of oni began, only a few of Kamigawa's ogres remained in the bitter cold of the Tendo Peaks. Most were drawn to the darkness of Takenuma. (Deathcurse Ogre)

"Although nowhere on Kamigawa was safe during the war, the Takenuma Swamp was the most horrifying. The rotting bamboo itself rebelled against its mortal inhabitants, pulling them into unmarked graves." -Observations of the Kami War (Pull Under)
