The most interesting part of Star Wars: The Old Republic’s player housing is that it is very customizable – you can decorate your stronghold with decorations picked up from across the galaxy, and position the decorations within your stronghold using the hooks system. Players mix and match decorations to create unique combinations and scenes within their stronghold.
