Taeshalach is the sword of the titan Aggramar. In his Antorus encounter, Taeshalach could summon fire elementals called the Ember of Taeshalach, Flame of Taeshalach, and Manifestation of Taeshalach.
In the RPG
Taeshalach (meaning "Flame Rend") is a sword that was forged from one of the two Shatterbound fragments of Gorshalach, and embodies all that is noble and good. When Gorshalach sundered itself, Sargeras abandoned the fragment that would form Taeshalach, as it was useless to him in his corrupted state. Aggramar eventually claimed the fragment and reforged it into its current form, which he currently wields as his weapon. If this weapon is ever combined with the other fragment, which has been reforged into Gorribal, Gorshalach will be reborn.
- The non-canonical RPG's origins are contradicted, as in canon, Sargeras and Aggramar's weapons were always different, separate blades. Then, both swords shattered in a duel when Sargeras betrayed the Pantheon.
