Genius Loci

A genius loci is difficult to spot, since it looks like any other section of landscape. A genius loci itself has no intelligence, but rather “emulates” the sentience of any creature it currently enslaves, if any. Each genius loci has only a single enslaved creature at one time, though other creatures may also inhabit the surface of the genius loci. Any creature entering a genius loci who is especially attuned with magic or nature may realize that something is amiss, though it is difficult to tell exactly what. Genius loci do not speak directly, though they may do so through their currently enslaved thrall.

Origin/Ancestry

The leftover destructive magic from large battles between the Ancient Elves and Ancient Dragons‌ was imbued in the land itself and created the Genius Loci.
