In PHN, these four (and some others) come together to make a group dubbed "Boys Club".

Boys Club actually ends up making a magical treehouse with little bits of themself and magic in there!


The relationship chart is something like:
--------
Galloway <---- loves ----> Kajeel

Kajeel <---- they coonodle ----> Byg Marco

Byg Marco <---- loves ----> Hex

Hex <---- important// family ----> Kajeel

Galloway <---- friends ----> Hex

Byg Marco <---- friends ----> Galloway

.

_(It should be said that Hex, Kajeel and Byg Marco are not my characters)_
