The Danuar built two entrances to their Mysticarium. Only the owners of Sillus Fortress can use the second.
As a member of [%userguildname] Legion, masters of Sillus Fortress, you may use any entrance you like.
Unfortunately, your Legion isn't in control of Sillus Fortress, so you can't use the special entrance to the Danuar Mysticarium.
While you are a member of [%userguildname] Legion, and thus are authorized to use the special entrance to the Danuar Mysticarium...
I don't think you're ready yet, [%username].
