Remember the Treant Christmas event?

[Nvr]

Remember around the time when FFXI was released in the US and that treant christmas event?

For those who don't, there was 1 treant in each region with, if i remember right, christmas lights on its branches. You could only engage the treant after talking to a moogle to temporarily reduce your lvl to 20. Basically, the entire server would throw bodies at these treants in an effort to kill them. It was awesome.

I was very new to the game at the time, so if anyone can refresh my memory on what the reward for killing these treants was I would appreciate it.
