Theory: The tools of Taborlin and the gifts from Auri are the items in the Lackless rhyme

Proposal
As mention in the theory of Auri's gifts to Kvothe matching the tools of Taborlin, excepting the ring for keeping secrets. Alone they can't be said to have a strong connection to the Lackless rhyme, but together they make a stronger case.

Reasoning
A ring, dreams, and secrets are mentioned in the Lackless rhymes. The fact that the Lackless box could be related to the box used to steal the moon[Reference needed] could also be related in part of the key being described as unlocking the moon. The Taborlin's tools being mentioned attributes significance to the items, as he is described as a historical figure of great power[Reference needed]. This indicates that Auri's gifts more than random items because of their connection.

The argument then is that the items are part of rhyme because of the descriptions of the gifts and the implied importance of them through the connection to Taborlin.
