Well the easiest way to name a character is using Latin. For more fantasy based names I would recommend reading the character lists for Tolkien's extended universe or putting together various phonemic sounds from a language(Latin-based, Germanic, Slavic, Asian, aboriginal, native Alaskan/American etc.) to make a nonsense but cool sounding name. Ex. The names I made for the DnD characters that me and my brother never use: Thirinir(Elven mage) and Banarok(Dwarven fighter)
