The Seven Cities were the cities of the elves, destroyed or taken over by the Horsekin in the Year -5 (over a thousand years before the main/current timeline of the novels). The Seven Cities included:
- Rinbaladelan of the Fair Towers
- Tanbalapalim of the Wide River
- Bravelmelim of the Rainbow Bridges
In the main/current timeline of the novels, some of the cities lie in ruin whilst the Gel da'Thae (the ancestors of the Horsekin who invaded the cities) still live in (or close to) some of the others.
