He knows that most of these are just thoughts as they came to them, and there is an element of it more prone to instigating thoughts than facts in themselves. Istredd can look at any of these and it spins him off into other theories, it works better when within a conversation. He wouldn't try to make this come off as more than ideas, ideas are sometimes all you have. Until someone else comes along and perhaps knows a fact.

"It has been brought up that we could intentionally try to summon the gods. In theory, if a blood sacrifice has done that, and they created a spell to send the entity back, it would be possible to refine both. Summon a god for questions, send it away." Istredd shrugs, looking at the board. That particular idea isn't written out there, because it's already in their minds. "I was the one to refuse to try anything like that until we had a guaranteed ability to dispel them."

Otherwise they were looking at maybe something worse than the heralds. Retribution, perhaps, from a god offended by the idea.

"If there is a way to test any of them, I would do it. The more we look into this, the more I think we really do have to summon one to get any answers." It's just not the smartest choice. It's dangerous. But who are they going to get answers out of otherwise? Solvunn? Unlikely. "Kyle's theory that they're not originally from this world is interesting."
