Have you finished a quest Alzbeta is involved in?
Are you stuck as in you don't know what to do, or stuck as in you can not get out? If the latter, can you not leave the way you came in?
Welcome to the forum.

BTW, if you edit your 3 other posts about this, there is a 'Delete Post' button beside the 'Change Post' and preview buttons, which will remove the topic, as well (as long as nobody replies to them).
