The dragons are the victims of a magical experiment gone wrong
Cloudy sky
Necro mount
The horse can be found at the foot of Storm Claw Tower.
I managed to get on top of one of the towers (the teleport worked this time)
A duel without a victor
(the left one is White Head from the previous post)
Bamboo forest
Ashos
If you take this artifact...
... then Ashos will be overrun by Orcs. The artifact protects the city from their attacks. I really regretted taking the artifact in my previous playthrough, but it was necessary to progress in the main quest.
I have explored most of the area north of the river Gon. South of the river live the Orcs and this area is a wasteland with the exception of Ashos and the bamboo forests in the western part of this area. I only made a short detour into the wasteland and quickly returned to Ashos to do a few side quests. Since I don't particularly like the wasteland, I'm done exploring the game. Exploring and the associated grinding were my main activities in the game. Now that these are gone, I don't see much point in continuing to play the game, as the side quests alone don't cut it plus I killed the majority of the opponents and these don't respawn.
As I mentioned in a previous post, most side quests were simple fetch/kill things quests. For some of the quests, the solution was illogical. Example:
In Ashos, two siblings are fighting over the inheritance, a forge. The quest could only be solved by killing one of them.
Yes, Skyrim has fetch/kill things side quests, too, however I somehow feel more connected to their story and the fates of the quest givers. Maybe it's due to fact that I see a lot of cloned NPCs in Two Worlds.
Long story short, Two World's side quests lack a lot of immersion. Does that make it a bad game? It depends on what you focus on. If you're after a good story and interesting side quests, then I wouldn't recommend the game. If you like exploration with a diverse selection of weapons, armor, enemies and locations, you might have fun with the game - I did until there was nothing left worth exploring.
