Tos'un Armgo

Tos'un Armgo is a drow of House Barrison Del'Armgo and part of a band of four, including Ad'non Kareese, Donnia Soldou and Kaer'lic Suun Wett. He joined this group after the Menzoberranzan raid on Mithral Hall went wrong. He is the occasional lover of Kaer'lic.

Drizzt eventually catches up with Donnia and Ad'non and slays them. Kaer'lic is killed by Obould and Tos'un is left by himself.

Currently
Of the four original Drow, only Tos'un is still alive, two of his companions having been killed by Drizzt, and the last, Donnia Suldue, a priestess of Lloth and his consort, having been killed by Obould after she attempted to kill both him and Drizzt. He now wields Khazid'hea, which he found in the discarded armor of Obould after Obould's battle with Drizzt.³

Tos'un begins feeling an unreasonable need to help his surface elf neighbors, when a group of orcs, well organized, raids the Moonwood. This raises several internal questions for Tos'un, and once discovered by Drizzt, Tos'un is persuaded to assist the drow ranger in his battle against the orcs.

Tos'un becomes the father of two half-drow/half-elf children, and now lives peacefully with the elves of the Moonwood.4
