Following their defeat at Dun Modr, the orcs were forced to retreat south, across the Thandol Valley to a secondary outpost at Dun Algaz. Anduin Lothar, hoping to push the orcs even further back into Khaz Modan, ordered the destruction of the outpost.
- The Warcraft II game demo has a mission called Thandol that is situated in Khaz Modan. If not a separate location, it could be an earlier, production name for the area.
- The name "Thandol Valley" hasn't been used since Warcraft II and might have been retconned out.
- Dun Modr was originally depicted as north of the Thandol Span in older sources including Warcraft II and Day of the Dragon. In World of Warcraft the early concept maps still followed that depiction, but the location of the city was eventually moved south of the Span.
- Similarly, Dun Algaz was originally depicted in Warcraft II as on the southern end of the Span, a place currently occupied in World of Warcraft by Dun Modr.
