We would very tentatively say the short answer to this is no. At least from the info provided by the link. Just to be sure, these seem to essentially be parts of people, like guardian spirits? And it seems like they can be sealed or driven away by trauma and other things, we're guessing. ... If that is the case, then, yes, in most instances, Lalli likely won't be able to manifest it--though we will let you know if this changes, since it could vary from Alice World to Alice World.

He might, however, find it accessible when his own World comes up. We can discuss it more in detail if you'd like here, just so we can make sure we have the full picture of how exactly the luonto work. Without knowing Lalli's canon one hundred percent, we can't say with absolute certainty if it would be allowable or not, so the default answer after reading the link is a no.
