Military action
Thinw, as well as some of Ankan's other generals, betrayed the Abreth .
After many years of fighting, as well as being yelled at by Ankan, the brightest of the Old Northern Men, Thinw, Ankan's prized general, took two other generals of Ankan's, Banður the dwarf and Mílían the elf, attacked Ankan, but they were no match for a god, so they were thrown to the walls of their mountainous garrison. Ankan then fled to the Underdark. The generals then opened the gates and joined the Waesws.
