Droids
Designed to serve a particular function, droids do not actually possess sentience. However, their programming can be such that, when hacked, some droids can give the illusion of sentience and function similarly to other living creatures. It must be noted that most creatures understand this and may, likely, still view them as nothing more than a tool.
A droids height and weight will vary based on many factors, mostly revolving around the purpose of their design. Energy consumption is just as diverse as their android and cyborg counterparts, which ever source fuels their cores is what they will require to continue functioning. And much like Bionics, so long as upkeep is maintained they can, theoretically, live for an eternity. The difference between a droid and other beings is they do not require a memory core to continue running as droids only require the most basic of programming to function.
Culture
Droids tend to adopt the cultures of their creator. Wanting to serve their purpose to best suit that individual's needs, they are often programmed to adopt traits to put the beings they work for at ease. Being built to serve does not leave many droids with a strong will of their own. It is rare that a droid will ever disagree with a sentient being, unless they believe doing so will keep that person safe. They possess a selflessness that is unprecedented among others, as they are unable to feel fear. That said, hacked droids have been known to colonize, though these colonies are often wiped out by humans who fear the consequences of what rogue droid factions might bring.
