You'll need to mount one or more docking modules on your Nephilim. You can get these in one of two ways:
1. Construct a player base, build a docking module factory on it, and construct a docking module (instructions are here). OR
2. Make an in-roleplay post in the Open Market requesting to buy one.
The first option is expensive, tedious, and time-consuming. The second option is just expensive.
Also, I'll go ahead and use my SUPER POWERS move this to a better forum section.
