I wish you luck on your crusade to Unrest, but do not think you shall ever be able to turn the tide of that detestable Estate. Quellious herself has already intervened in that place of brutality, banishing a brutal dwarf to eternal purgatory in the halls of the Estate. She will not permit him to pass to Brell's great halls.
When you do venture to the Estate of Unrest, please take the personal quest to remind Garanel of his inability to leave this plane, its the least one can do for
Serra.
