I disagree. We have no right to infer Nanika is a product of the Dark Continent. The known casualties have all been collected. If we theorize how Alluka may have come in contact with an entity from the Dark Continent, we end up making assumptions, which is another word for speculations. Nanika is accepted by all members of Alluka's family as a second personality, even by Killua. Silva stated they do not know where Nanika came from, but this does not constitute definite proof it is not just a product of Alluka's mind and aura and is instead "unworldly". As of now, we should consider it as a second personality, as all the Zoldycks do. The two possibilities are not at all equal.

Your statemement about the Dark Expedition arc is rooted in speculation. What is your proof that powers beyond Nen exist that can influence reality? Can you demonstrate Nanika uses them? We definitely know Nanika uses aura, as clearly stated during the last election. Nen is the use of aura. Thus there can be no arguing that she is a Nen user, because this is what the manga hinted until now. We can't assume there is going to be some big revelation about Nanika's powers.

Having accepted that Nanika is a Nen user, her ability is definitely Specialization (and has limitations just like any Nen ability does), it cannot fall under any other type. If this does not sit well with you, we can discuss it further; however, a "genius" is a person who can, consciously or not, use Nen abilities without training, and Alluka/Nanika perfectly matches this definition, since we should go with what the characters tell us and not what we guess basing on future arcs.
