These are concepts I created for Fel structures of the Burning Legion, a vast innumerable army of demons and corrupted races, seemly invincible and unstoppable who seek to destroy all life and doom the universe to eternal darkness.
Since World of Warcraft has its roots in Warcraft, which has its roots as a RTS game, we wanted utilize that in our thinking process for the creation of their buildings and culture kit. How are they created? Would they build like humans? How would they take over an area? What would be the first structure to establish a base? What's their tech tree? Fun stuff to think about and nerd out on.
I also want to thank Patrick Faulwetter for his contributions to the Burning Legion structures during the early development phase.
