Hatari (known as Hatary in PAL region game versions) is a long lost kingdom on the continent of Tellius in the game Fire Emblem: Radiant Dawn and it is innhabited by Wolf tribe Laguz. It is ruled by Queen Nailah.
The culture of Hatari is notably different then other cultures in Tellius. If Nailah fights Dheginsea in the Part IV Endgame, it is revealed that Beorc and Laguz live peacefully together along with Branded, the only known nation where Branded are not shunned at the time of Radiant Dawn. This is most likely owed to the fact that Hatari has been very isolated from the continent's other nations - until Nailah met Rafiel, she believed that her nation was the only one to survive the great flood. As such, the lies that Begnion spread about beorc/laguz relations being a crime against the goddess never reached their ears. It is currently the only known region to be inhabited by Wolves. There are no generic wolves in the game, and there are only two known inhabitants. Thus, very little is known about the nation itself.
Hatari's name is likely taken from the Swahili word of the same spelling which has the meaning 'hazard' or 'peril'.
