Armando, Izdahl and Dagmar are all seeking the truth, in different ways, in The Architect’s Guardian, Chapter 47. Here’s an excerpt:
Armando chose not to offer a denial about Dagmar’s speculation, as doing so would have sounded hollow. Dagmar didn’t press for an answer. He wasn’t particularly interested in one, as there was a larger matter. As opposed to what he’d led Armando to believe, the shield wasn’t the reason he’d wanted the architect in his home.
