The Dwarven ruins of Raghthar are said to exist somewhere adrift from this physical plane, this might explain why its sole entrance may appear in many different places at the same time. One just needs the ability to harmonize its doorway with our exact location and time, and then unlock it. Luckily for us Aelif has this ability, and it turns out many others which one might have considered to be far beyond the skill-set of an agent of the Fighter’s Guild.
Skeletons under mystical barriers, Dwemer traps, Auroran battlemages, and accusations of the dead. This Fighter’s Guild is like a Tsaesci council chamber, I trust none of them save perhaps Merric; and yet I fear his blind virtue most.
