Battlegrounds for lvl20-29 ?

[velt]

i read somewhere on Outspark's forums that there is a place called the *something* of Abyss, that is a PVP arena for level 20-29 players.
However, the wiki here only mentions places for lvl30 and up.

So, can you tell me a bit more about the PvP maps ?
What are they called ?
Where are they ?
What happens when you're killed by another player, or when you kill one ?
Are there still monsters on the PvP maps ?
Are their drops normal or better than usual ?

i know it's a lot of questions, but I want greeeeens
