Medusa used to be the highest level of EO for a very long time. Newbs would say that she was the best player but... not exactly. She was also one of the most annoying players and ill explain why.
The weirdest and most recognizable aspect of Medusa is how she thought she owned a spot in Endless Online. Where ever she trained, she would claim it as her own and expect others to leave as soon as she arrived.
I've always been against ksing, if I see you training peacefully in a spot, I think the nice thing for me to do is look for another spot to train in, but Medusa wouldn't let a little thing like niceness screw with her exp.
It didn't matter if you had been in that spot all day, once she logged on, she would tell you to leave because it was ''hers''.
In the screenie, I was in the spot for a long time training peacefully when she logged on and expected me to leave, but since I got tired of letting her boss me and everyone else around, I decided to stay.

She was known for not talking much which was good because whenever she opened her mouth it would be to either threaten you with getting walled by Admins or random insults that don't make sense as the ones you see in the screenie. Even her guild members would say that they never saw her talking in guild chat, except to ask for help against Kill stealers.
In the screenie, you see her blaming Marlina. At the time Marlina was behind of Medusa in level but very close. I didn't even know Marlina but Medusa would use any excuse to send guild members to ks her.
The Guild Members weren't so good either. She would have an entire guild so she could use them to help her get more exp, since leveling was the most important thing to her. They would just follow orders without even really knowing who she was. Just a bunch of newbs who joined because they thought that by being in the same guild as the highest leveled player, it would somehow make them less newb.
So why rant about all of this?
It is important to not let ''power'' get to your head. To think just because you have higher level, more gold, or a bigger guild, that it gives you the right to boss others around.
This is what I call the Medusa Syndrome.
