Eastern Antonica Area - The eastern part of the continent of Antonica is a very varied place. First off, the Halfling City of Rivervale is connected to Misty Thicket, also one of the best newbie areas in the game. In fact, it is so good Eve isk; many Human players make the extremely dangerous trip here just to level.
If you do play a human, and you do want to make the trip to Misty Thicket, you have a dangerous trip ahead of you. Firstly, you need to run through the Eastern and Western Common lands, before coming to the "hell zone" of Kithicor Forest.
From about 8am (game time) to 6pm, Kith Forest is saving for travelers. But, as soon as the sun sets, the forest turns into a haven of death. Level 30+ Undead spawn, slaughtering all in their way.
Worse yet, high level players tend to pull the monsters to the zone lines to safely fight them. If you need to run through Kithicor, do it in daylight and be sure to /shout "Undead gone?" upon entering the zone.
As for the mobs in Misty Thicket, they are basically the same as the ones in the Qeynos area, but with Goblin Workers taking the place of Gnoll Pups. So, take snakes at level one, then Goblin Workers, Beetles, Rats, and Spider-lings all the way to four.
