Grom'gar is the ancestral home of the Thunderlord orc clan located in Frostfire Ridge. According to legend, Grom'gar was built in the skeletal remains of the last colossal, which was supposedly killed by the Thunderlords many generations ago.
- During the beta, it was referred to as Thunderfall and Kron'mar.
"Grom" is likely the Orcish word for "colossal" (see colossal speculation). The meaning of "gar" is uncertain, but as "gar", "mar" and "ar" are all commonly seen suffixes in the names of orcish towns and settlements, they likely mean something similar to "city" or "village".
- Patch 6.0.2 (2014-10-14): Added.
