The Eleint
They do not play a large role in the Malazan world because they are not from there. The Eleint created the warrens at the order of K'rul. Eleints share ownership of the warrens with each other, so that one warren may have three dragons associated with it rather than only one. K'rul and his Eleint are the sources of sorcery, creators of the warrens and K'rul is the path-shaper. The Soletaken are children of Tiam, yet are not pure-blood Eleint, however they do possess the power of the Eleint. They are free to go where they please and have become a problem for the warrens, for every gate is a wound to the warren. Scabandari Bloodeye is blamed for doing the first harm to the warrens when he created a gate in Kurald Emurlahn.
