Gods of Larkspur include:
The gods of Larkspur are able, very rarely, to have offspring, who will be great mortal heroes along the line of Hercules. However, the 'rules' do not allow anyone to continue indefinitely in a half-and-half state like this, and godchildren must eventually either choose to become mortal or face a Test to earn full godhood. If the Test is failed, the godchild becomes mortal anyway, if not killed during the Test.
Godchildren can be quite different from their parent gods in nature and talents. What they don't have is a choice about the "great heroes" deal. Trying to resist this can result in hilarious consequences.
