Immortals are an order of knights who once guarded the city of “_”. Upon reaching a certain age or status, they were offered to join the ranks of the immortals. They abandoned their bodies, and possessed the armor they wore into battle. They look like armored knights in all respects except that they wear no helmets. Instead a hooded cloak is attached to their armor, and anyone looking within will see a swirling blackness.
The means to become an immortal are supposedly still recorded within the city of “__”.
Titans are powerful constructs generally resembling people, used to defend the lost city of “_”. These beings are soulless, and powered by arcane energy flowing from the city itself. Over the years since the fall of man, the energy has become unstable, and the titans have as well.
A zombie differs from normal undead, as it is created through an eldrich ritual cast upon a fresh corpse. The corpse will not age, it has inhuman strength, and feels no pain, but it also has no free will. It will follow it’s commands to the letter, but will be unable to improvise.
