Iriali One and Secret Project?

[18th Shard]

What if Virtuosity is the One of the Iriali?

The Coppermind records, "The Iriali worship a god they call 'The One'. According to this belief, the One knew everything but had experienced nothing. And so the One became Many in order to experience all things. As each experience is different, it brings completeness to the One. Eventually, all will be gathered back in when the sum of land is attained and they will once again become One. Every person is a different mind of a single being experiencing different lives. As Many, they need ignorance. Each fragment of the One’s mind has its own body with different passions and inclinations. They exist in variety to experience all kinds of thought. That means some people must know and others must not. Just like some people must be rich and others poor."

We are told in SP#3 that "Virtuosity splintered herself" near Painter and Yumi's planets. Why would a Shard splinter itself? Brandon said in a livestream that between the Shattering of Adonalsium and the Splintering of Virtuosity, she was "exploring the artistic expressions of the cosmere and choosing not to settle in one location." Perhaps she knew everything about the art of the cosmere as then present, but wanted to experience it herself. Perhaps this is why nightmares and the spirits Yumi sees are drawn to art. 

If true, this would mean the Iriali most likely left one of these two planets before going to Lumar and Roshar.

Possible. i think the fan consensus is that this refers to Adonalsium, since he had all of the shardic powers he could truly be said to "know everything" (or at least as close as you can get in the Cosmere). Any shard, while powerful, must be at least 1/16th of his power/knowledge.
