NOTES:

If a tehta intersects with the telco of a tengwa, hold Shift to place it above.

Some tengwar have capitalized variants - T, S, and K. These represent th, sh, and gh, respectively.

Long vowels are written with both upper and lower tehtar; broom would be typed brUum. If this is not possible, the long vowel marker (typed with a capital J) is used; "thee" would be typed tIiH or tIJ.

Vowels at the end of a word are written below a vowel marker, typed with a capital H.

Three abbreviations are present: @, &, and _, representing ash (a/one), agh (and), and ishi (in/inside), respectively. More may be added. 

My interpretation of a variation of the Tengwar optimized for Blackspeech and rendered in a unique style commissioned by the Dark Lord Himself.

Something to note: The symbol for th is represented by what should be the symbol for f, and the symbol for s is represented by what should be the symbol for th. This was to keep a consistent one base wide width for all of the characters. As well, nonstandard forms of h, s, z, l, and r were chosen specifically to keep the consistency between letters to an absolute maximum.

This font was inspired by the works of Christophe Szpajdel (Lord of the Logos, 2010, Die Gestalten Verlag), as well as by the film trilogy and the following game titles (e.g. Middle-earth: Shadows of Mordor, Warner Bros. Interactive Entertainment, 2014) based on Tolkien's epic masterpiece, The Lord of the Rings. Given the game theme, and the 48 bricks vertical limit, I thought more or less around pixel art, or pixel fonts. This is my endeavour to make a spiky blackletter in Szpajdel's black metal style that evokes the terror of Mordor at pixel level. This font has been extensively tested for best kerning, yet some issues might have remained unresolved.
