Unplottable Place Rendering Spell

This spell was used by Cuthbert Sinclair to rendered a place (his secret hideout) became invisible and unplottable in Blade Runners. It maybe a branch or maybe strongest known form of warding spell.

According to Men of Letters's "Infamati et obliterati" (Dishonored and Forgotten) members files, at 1954 (2 years before his "formal separation" in 1956), he found (or maybe invented) this spell and proposed the usage of this spell to rendered The Men-of-Letters Bunker unplottable and only could be accessed by special countering spell. His proposal later to usage of the spell later rejected by Men of Letters and later he kicked out in 1956. However, it wasn't the end. He later used this spell to rendered his own mansion became invisible and unplottable.

Procedure
Not much known about the spell. The procedure of this spell also never be shown. However, once casted, the spell extremely and heavily warded the place where the spell was casted and the place became invisible and unplottable. The casted place will be unplottable in indefinitely time, even the caster of the spell is died. So, none can't break this spell.

Countering
The only known way to counter the spell is Unplottable Place Accessing Spell as the entrance of the warded place.
