Bold Fraktur, in almost every case. It is the only blackletter alphabet in Unicode with all twenty-six capitals and all twenty-six lowercase letters present, so nothing in your word quietly falls back to a different weight halfway through. Plain Fraktur is missing five capitals, C, H, I, R and Z, which are filled in from an older part of Unicode at a lighter weight.
Two things it cannot do. It cannot give you numbers, because Unicode has no blackletter digits whatsoever, so a year in a medieval title has to come from one of the six styles that do convert digits. And it cannot give you a drop capital, an illuminated initial or a flourish, because each of those was painted for one particular letter on one particular page. If you want a single ornate initial, the full A to Z chart lets you copy one letter at a time, which is usually what that request really is.
For a poster, a game map or anything that will be printed rather than typed into a box, characters are the wrong tool entirely. The homepage sets your words in eight real typefaces, Texturina among them, a textura, which is the one script Unicode is missing, and exports a PNG at three times the size on screen. The SVG scales without limit but names the typeface rather than carrying it, so it only prints correctly on a machine with that face installed.
