Find Napachee in Alaska.
Ask Napachee 'language'
Napachee Kadlak says to you, 'If you are interested in learning our language, just say so and I'd be happy to teach you.
Ask Napachee ' I am interested'
Napachee Kadlak says to you, 'Ah, good! If you follow me, I will show you things and teach you their names.'
Follow Napachee.
He will lead you around, pointing out various items, and asking you to repeat after him. Simply say the word he's pointed out.
When done, you will receive Xp and the whois! ( and the other Inuit mobs will now be able to understand you because you are able to speak their language.)
