Una sombra se cierne
El sueño de Morgana y los susurros de Isabella hablan de un ataque a la fortaleza de los guardianes del alma de Caer Dun. Apresúrate a Caer Dun e investiga.

QUEST BUGADA!!!!
Can’t not finish quest due to boss not spawning in soul trail…
:(
Tried everything
Quest bugged, can't enter the solo trial.
• Fixed an issue of being unable to progress the quest “A Shadow Falls”.
Should be fixed now according to this official post.
same problem... how am I supposed to do the artifact quest if I have to do this quest chain first? :(
tenho o mesmo problema
Tô com o mesmo problema.
I can't use the Staff to enter the portal. Name Quest: A Shadow Falls - Enter the Corrupted Cave. :(
diid anyone of you got a solution?
I'm also having the bug that these other two are having
I have that same issue. You are not the only one either. I have submitted a ticket to AGS with logs, screenshots, server name, etc so hopefully it should be fixed at some point. I did try reseting the quest too but still yielded the same result. Is this part of the main quest arc to get to the new area?
The Quest part where you need to get into the Cave seems to be bugged. When you walk up to the Cave Entrance it shows a message "Soul Trial Completed" without any interact function.
Quest bugged for me too
