Ignis would be very willing to help with this! He doesn't really collect things so much, but he has been here from the beginning, so any event write ups Legion might want, he can give. He will just need someone to write them down since much to his displeasure of all the skills he's gotten better at since losing his vision, writing is not one of them. LOL!

Oh! I just remembered, he does have a datapad he can pass onto Legion for adding to the museum. It's the one from this post. He also has a honeycomb hammer he can pass along from everyone's adventures fighting the Clown Box.

Goodness, he has more stuff than I thought he did!
