The grimoire shown by the second neutral faction was met with interest by several clans. Although they still had to validate their claim that the Four Greatest Minds wrote it, there was no harm in investing in it. Even if the grimoire's author turned out to be different, it should still have value depending on its content.
Muffled discussions among leaders and representatives followed soon after, and the second neutral faction's spokesperson smiled in satisfaction. When he declared the origin of the grimoire in his position, his faction was already 60-70% sure that the Four Greatest Minds wrote it. The remaining 30-40% were only to validate it further by cross-referencing some documents that the other clans had in their possession that belonged to them.
While the spokesperson was waiting for the congregation to start voicing their offer, he was immediately silenced by the first one.
