The Real Culprit
The archbishop took Professor Heinrich from the academy, it was said that he was locked up in Oxwade prison for a few days before he was judged.
The basis for his arrest was his confession as the person who created Cannabis in front of Allen and Hussain. As a paladin who had served the church for most of his life, Wyclieff's testimony was considered valid. Although his opinions were always regarded as radical, he never lied and was highly trusted by the church.
"You're really unexpected, Allen. To try to get serious against Helig Wyclieff," Hussain said.
The two of them were still in the alchemy room. Since some plants were already frozen, Hussain told Allen to put them in the next room where it was hotter. He had intended to take it home since Professor Heinrich trusted him to keep it, but Hussain forced him to leave it behind.
"What are we going to do now?" asked Allen.
"Proceeding according to plan, of course."
