Ignan

Ignan is a dialect of Kalimag, the elemental language, spoken by fire elementals.

In the RPG
Ignan is the language spoken by fire elementals from the Firelands. It is also known by conglomerates with the sub-type of fire. The half-elf banshee, Ielephia also knew the language.

The term Ignan shows up in the Kalimag phrase, "Ignan'kitch" in the Kalimag language parser.

Speculation
The names of the runes of warding in Molten Core (Kress, Mohn, Blaz, Zeth, Mazj, Koro and Theri) may be Ignan.

Trivia
"Ignan" has an apparent connection to DnD derived generic languages, which apparently can be found in DnD rule books.
