The Fall of the House of Usher
(Auto-generated)

Perhaps the eye of a scrutinizing observer might have discovered a barely perceptible fissure, which, extending from the roof of the building in front, made its way down the wall in a zigzag direction, until it became lost in the sullen waters of the tarn.†

fissure = long, narrow crack or split; or creation of one
The radiance was that of the full, setting, and blood-red moon, which now shone vividly through that once barely-discernible fissure, of which I have before spoken as extending from the roof of the building, in a zigzag direction, to the base.†
While I gazed, this fissure rapidly widened—there came a fierce breath of the whirlwind—the entire orb of the satellite burst at once upon my sight—my brain reeled as I saw the mighty walls rushing asunder—there was a long tumultuous shouting sound like the voice of a thousand waters—and the deep and dank tarn at my feet closed sullenly and silently over the fragments of the "House of Usher."†
