If memory serves, this quest chain begins with Holgunn after re-capturing Fort Virak. He directs the avatar to contact the chieftain at Kragenmoor, far to to the south. When the chief is contacted, he directs the avatar to meet with his senechal, who proceeds to give various quests to the avatar.

One such quest, Save the Son, is to rescue the chieftain's son, "Sen", from captivity in the nearby mine. So my avatar entered the mine and fought his way through the maze to the location where the son was supposedly being held.

However, the cage of iron bars contained only an empty stool on which the absent prisoner could sit. Also, I did not see any evident door to the cage, whether locked. I don't believe that I ever was apprised of any particular requirement to acquire and use a key or other instrument, only to find the location of the son.

At the same time that my avatar was approaching the cage, another player's avatar ran past mine to the cage. After I arrived and found the cage empty, the other player's avatar jumped from the location to the floor near the entrance below and began fighting the re-spawned mobs that my avatar had previously encountered. Evidently he intended to exit the mine via the same tunnel through which each of us, respectively, had entered it.

So I supposed that the other player's avatar had released Sen from the cage before I arrived. I waited for Sen to re-spawn but nothing happened. So it seemed possible that my avatar was given credit for the release, too, if that had happened.

When I returned to the quest-giver, she only responded as though my avatar had not completed the quest and offered no access to the previous conversation during which it was given. Also, there was nothing in the Journal that would signify that my avatar needed to do anything other than to find "Sen" in the mine.

So my avatar returned to the mine and proceded to fight his way again to the location of Sen. In the large room through which he moves to the last tunnel leading to Sen's location, there is a door on the north wall that was previously inactive. The avatar of the other player suddenly arrived on the scene again and used that door to exit. However, my avatar could not follow him. Evidently there is some presumption that an avatar will use that door to exit after releasing Sen instead of returning to the entrance. As to when the player might be instructed to do that, I don't know.

After the other avatar's exit, my avatar continued to fight his way to Sen's location again. However, the cage remained empty. I logged-out to the character selection screen and took a break. When I resumed, nothing had changed, the cage was still empty. So I returned to the quest-giver, but that was no good, nor was running the dungeon again for the third time any different as to outcome.

Reluctantly, I decided to abandon the quest and pick it up again. I've never done that before in TESO but it is easy to do in WoW. However, after I abandoned it, the quest-giver for "Save the Son" had vanished and I could not find her anywhere on the map. The chieftain still thought I was looking for his son. None of the NPCs which my avatar had to locate and talk with (in order to meet the chieftain after leaving Holugunn at Fort Virak) were still present. When my avatar returned to Holgunn today, the coversation was simply a repeat of the remarks that Holgunn had made after my avatar had accepted the quest to go to Kragenmoor to seek the aid of the chieftain.

This is very, very demoralizing. Unfortunately, I not only have a lot of time and effort invested in the quest, but also in the story-line. As things stand, I cannot complete the uber-quest to re-imprison the second Brother in his tower (- ? -). If this sort of disaster is a common occurrence, then please let me know so that I won't waste any more time and effort playing TESO.

Please advise.
