Some rules for reference, and to make sure all the translation projects stay as much in sync as possible.
Names
Names of people are capitalized.
Nicknames/sobriquets (such as Hero of the North, Monster of Greatskull Mountain) are capitalized.
Places
Places are capitalized if they are proper nouns (such as Carpe Kingdom, Skull Empire). When referred to as simply the kingdom or the empire, they are not capitalized.
Relationships, Occupations and Titles
Family relationships, occupations and titles/positions are handled the same way. When used as common nouns, they aren’t capitalized (such as my mother, the queen, the paladin). When used in front of or in place of the person’s name, they are capitalized.
Example: Ah, my mother is here. Hello, Mother, let me introduce you to Adventurer Helena.
Institutions
Institution names are capitalized (such as Adventurers’ Association, Magic Tower). However when the names are shortened, they are not capitalized (such as the association, the tower, the labyrinth).
One notable exception is how we refer to religious institutions. The Church of Valtherus, when shortened, is still referred to as the Church. (This takes its cue from how the Catholic Church was referred to in the middle ages.)
Races
Other fantasy race names (orcs, trolls, elves etc), much like humans, are not capitalized. However if the race is part of a sobriquet that may be an exception (for example, Gwydd the Troll).
Items
Unique items, that are proper nouns, are capitalized (for example: Mace of Molog Bal). Non-unique items will mostly not be capitalized but this may change on a case-by-case basis.
More rules may be added in the future.
