Seems pretty clear that this is written from the perspective of a typical doomed HP Lovecraft or Clark Ashton Smith-type mystic anti-hero. Even the title seems borrowed from Lovecrafts' At the Mouth of Madness.
It starts with a typical HPL introduction where the figure explains from the beginning that this has already taken place in the past, and he is recounting the events from some changed and maybe unpleasant perspective. He's opened up some occult portal in search of power or secret knowledge, only to discover the truth is too terrible to comprehend without going mad, and he's released some terrible entities from the other side who seek to destroy him for what he's done, and prevent him from using the powers he's tried to gain. He tries to escape, thinking in his madness he can eventually outrun his fate and become the being he sought to be in the first place, but there is nowhere he can go where is isn't pursued. Everywhere he goes (maybe to the end of time and space), he sows insanity and destruction, until he is eventually caught and either destroyed or dragged back to the realm of his phantom pursuers.
