There is no single definitive answer as the "Lord of the Rings Name Generator" is not a specific, pre-existing tool with a fixed algorithm. Different generators will produce different results. To get a name fitting a "Captain of the Guard," consider these options, drawing inspiration from Tolkien's naming conventions:

Option 1 (Strong & Authoritative):

• Boromir: Evokes strength and leadership, referencing a prominent character. Variations could be Borin, Borwendil, or even a less common variation like Borlas.

• Faramir: Similar to Boromir, but potentially suggesting a more thoughtful and strategic captain. Variations could include Farnhold or Faramir's less common name, if the generator allows for such variations.

• Harnath: A strong-sounding name suggesting a warrior's spirit. Variations could include Harnulf or Harwend.

• Belethor: Suggests a steadfast and reliable captain. Variations could include Belegorn or Belemir.

Option 2 (Noble & Regal):

• Eomer: A name associated with Rohan, suggesting nobility and military prowess. Variations could include Eomund or Eorl.

• Aramir: A name that blends regal sounds with a sense of authority. Variations could include Aramiel or Arador.

• Aldor: Suggests wisdom and leadership. Variations could include Aldred or Aldric.

Option 3 (Stern & Experienced):

• Grimbeard: A name suggesting a veteran captain, possibly a dwarf or human of stern countenance. Variations could include Grimulf or Grimstone.

• Ironhelm: A name that evokes strength and resilience. Variations could include Ironclad or Steelhelm.

• Stonehand: Suggests a captain known for his unwavering resolve. Variations could include Stonewall or Rockhand.

Option 4 (More Subtle & Strategic):

• Arathorn: A name with a sense of quiet authority and wisdom. Variations could include Arathor or Arathriel.

• Halbarad: A name that suggests both strength and a degree of subtlety. Variations could include Haldir or Halbrand.

To get a specific name, you would need to use a Lord of the Rings name generator and input the parameters "Captain of the Guard," potentially specifying a race (human, elf, dwarf) or desired tone (strong, noble, stern, etc.). The generator would then use its algorithms to create a unique name based on those parameters. The names above are examples of what could be generated, but are not guaranteed outputs from any specific generator.
