Erhart can be found standing in front of an area that looks like a foundry, huge vats of superheated metal being poured into moulds behind and around them, backlit by molten, orange metal, his black armor looks almost crimson now. He says nothing, just holds the Black Sword in two hands, waiting for her near a gantry structure, standing at the foot of it, the top of it accessible by both stairs, a conveyor belt, and covered in dangling chains used to dip things into the huge metal mass below.

(Think the ending sequence of terminator 2)
