Welcome to Dalrath
Dalrath is a fantasy world created because reasons. This setting will assume the ruleset being used is 5e, and the races included in this setting will be based as such.
Mechanically, you’re fine to just use the PHB to create your character. If you wish to create a character based off in this world, then this wiki will be the repository of knowledge for this world. Information based on various races and the history included for such will be found on their respective pages.
