20 BBY 0 days after the jedi purge

I was fighting side by side with clones my master depa billaba kanan was close by then a clone commander pulled out a holographic device and the chancellor was on it and he told them to "execute order 66" I thoght nothing of it until he turned his gun to my master and shot her in the arm she whispered to kanan and I to "run" then the clone shot her in the head so he ran but I wanted revenge so I activated my lightsaber and the gold blade cut through hundreds of clones then one shot my arm and the commander picked up my lightsaber and cut my arm off. Then I ran to my starfighter r2-d26 got in the astromech droid port I took off and flew to the nearest planet I could find. I landed and I saw a skull with lots of battle droids broken around I check my holo map this was dathomir the planet of the witches so I decided to leave when a beast came lumbering towards me. It was about 7 or 8 meters tall with spikes on its back something about it was familiar and I remembered I saw something like that in jabba's palace . Think what was it ummmmmm it was a rancor it opened its mouth and roared I screamed and jumped into my ship I yelled at r2 but he wouldn't come so the rancor picked him up and plopped him in his mouth I took off but a bunch of clone ships were blocking my path one shot my engines and I began to fall to the planet below kklatooine.
