王楷 / Wang Kai (Late Han)
王楷 / Wang Kai (Late Han) enters the wiki through Hanji 974 as one of the participants in the secret Yanzhou betrayal discussion. The episode names him with 陈宫, 许汜, and 张超 before the group persuades 张邈 to invite 吕布 into 兖州.
The source keeps Wang Kai source-scoped and thin. His importance is collective: he marks the rebellion as a networked local-adviser move, not merely a spontaneous break between Cao Cao and Zhang Miao.
