"The Great General 大将军 (dà jiāng jūn)"
Who is he:
Every leader has their most loyal and trustworthy followers. Cao Ren was such a follower of Cao Cao 曹操. From Cao Cao's rise to power, till Cao Cao's death, Cao Ren was a formidable and trustworthy general in his camp that never once showed any signs of disloyalty nor surrender. In fact, Cao Ren saved Cao Cao's ass a couple of times. Yet it must be said that Cao Ren receives a lot less mention in the story than many other of Cao Cao's generals (such Xu Chu 许褚 and Dian Wei 典韦). Perhaps such is the fate of those who keep the world turning behind the scenes. Dr Goh Keng Swee was never as well known as Lee Kuan Yew was he?
Character ability: "Entrenched 据守 (jù shǒu)"
At the end phase of your turn, you can draw three cards, then you stack your character cards.
Difference from Normal SanGuoSha:
The ability description of “Entrenched” has been changed from “flip your character card” to “stack your character cards” to reflect the new execution for "skip a turn". Essentially, the ability works the same way.
Ability's Relation to Story:
This is an interesting one. There actually is one scene in the story where Cao Ren was entrenched in his city, pretty much helplessly on the defensive. When Guan Yu 关羽 attacked the city of Fan Cheng 樊城 where Cao Ren was situated, Guan Yu starved the city and flooded it by redirecting river flow. Despite the odds, Cao Ren kept his troops' morale up and held out till reinforcements came. This is probably where the "Entrenched" ability arises from. But if you ask me, it's kinda strange to base an ability on a dire circumstance! I'm not the biggest fan of this ability and i'm still researching (using Cao Ren as often as possible) on how to make this ability work to my advantage.
