Exterior Location #31 on the following map:
A massive Barrow complex with two entrances three-quarters of a cell apart. Please make sure the interior fits the exterior. My recommendation is to copy the two BM_KA_Door_Dark's and pasting them in your cell, so you can build the shell around the doors, at a proper relative position.
Please use the T_Imp_DngColBarrow set.66. Halanchek Barrow
The exterior file can be found in this thread.
Always use the latest file.
