Ah, Lambert thinks. In other words, a long time ago.

For now, he'll keep that thought to himself and manages a mostly-neutral nod at the statement, no opinion either way. Sure, he agrees in principle that more knowledge makes a better book, but that doesn't stop people from writing bad ones anyway. He can't gauge yet if Strange falls into the latter category or not.

But since he's claiming 'occult traditions' ...

"A couple of things," he says, after a pause. "Protective rituals and objects in a modern context is one. Supernatural bargains are another." He shrugs. "My research mostly involves trying to trace modern beliefs to their original origins, where I can, but it's hard to find anything..." Lambert pauses, trying to think of the word he's looking for. "...coherent."
