Prince Sebastian did not know what exactly lord Darth has planned so he decided to set a trap for him. It was better than the lord falling into his trap.
The prince and Jeffrey had this understanding before he came into the cave to pull the sword of destruction. Prince Sebastian was not hundred percent sure that he could pull the sword, but even if he was not able to pull out the sword out he still had other plans to deal with lord Darth.
To his surprise, on his first attempt to pull the sword it came off without any struggle. Prince Sebastian was shocked even Jeffery was shocked. Prince Sébastien then deliberately put it back to its place, the sword has already been stuck for so long, if a few people do not witness him pulling it out, a rumor might spread the following day that the sword was fake. Of that happened the internal war he has been trying to stop from happening for so long may happen.
